A quotation for a keyed sliding handle is incomplete until it identifies the lock mechanism, door interface and keying arrangement. By the end, you will have a measurement checklist and a comparison method for selecting consistent wholesale lots that fit the intended aluminium, uPVC, timber or glass system.
Key takeaways
- Confirm whether the quotation covers a handle, lock assembly or separate lock.
- Measure door thickness, cut-out dimensions, backset and spindle interface before ordering.
- Compare keying options, hook or bolt action, corrosion resistance and cycle performance.
- Record mechanism, dimensions, finish, testing documents and installation parts on the comparison sheet.
Identify the Exact Keyed Handle and Lock Mechanism
A quotation is incomplete until it says whether the sliding handle with key is a keyed handle only, a complete lock assembly, or a handle paired with a separate lock. Ask whether turning the handle directly drives hooks, a mortise bolt, an espagnolette gearbox or another locking component.
| Option | What the quotation must identify | What you receive |
|---|---|---|
| Keyed handle only | Handle type, cylinder, fixing centres and whether it locks handle rotation | A keyed handle without the internal door lock |
| Complete keyed sliding-door lock assembly | Handle, lock case or gearbox, hooks or bolts, cylinder, keeps and compatible profile | A matched operating and locking system |
| Handle paired with separate lock | Handle interface, lock brand or model, spindle or drive connection and cylinder specification | Two components that must work together |
Do not treat a surface-mounted pull as a locking assembly. It may provide grip while a separate hook lock or mortise lock does the security work. A recessed handle has different cut-out, depth and clearance requirements, so a visible match does not prove compatibility.
Request a drawing showing the closed-position projection, backset, mounting-hole centres, stile clearance and required cut-out. Ask whether the cylinder or lock cartridge can be replaced without changing the complete handle. A proprietary cartridge can turn a cheap replacement into a full hardware change.
Finally, demand cycle-life and operating-force data for the complete handle-and-lock combination, not the handle alone. A stiff operation often indicates sash misalignment, compressed seals or badly positioned keeps rather than a stronger lock.
Measure the Door, Handle and Hardware Interface Before Ordering
A handle that matches the cut-out can still fail if its spindle misses the gearbox or its screws do not reach the reinforcement. Measure the existing hardware with the sash open, then confirm the profile system, door thickness and lock-box depth with the supplier.
Record these dimensions before requesting a wholesale quotation:
- Screw-hole spacing, measured centre to centre; 43 mm fixing centres are common in espagnolette hardware but are not universal.
- Spindle cross-section and orientation; a 7 mm square spindle is common, but a different size will strip, bind or fail to turn the lock.
- Spindle length from the handle shoulder to its working end. Too short will not reach the gearbox; too long can bottom out and prevent the handle from seating.
- Handle-base footprint, backplate size, key-cylinder position and the required sash cut-out.
- Closed-position projection, backset and required clearance from the meeting stile, mosquito screen, curtain and adjacent sash.
- Profile material and section: aluminium, uPVC, timber or framed glass. Note internal reinforcement, lock-box depth, screw type and keep position.
| Measurement or detail | Confirm on the sample or drawing | If it is wrong |
|---|---|---|
| Fixing centres | Hole spacing and screw diameter | Loose or stripped fixing |
| Spindle | 7 mm square size and length | Handle turns without moving the lock |
| Backset and projection | Closed clearance and lock engagement | Hook or mortise fails to engage |
| Profile interface | Gearbox, reinforcement and keep | Correct-looking handle will not operate |
Require a dimensioned drawing or physical sample, not the phrase “standard handle.” Also ask whether the handle drives the lock directly or is paired with a separate hook, mortise or multipoint mechanism.
Compare Keying, Security and Operating Performance
Judge the complete handle-and-lock assembly, not the finish: confirm what the key immobilises, how the lock resists forced opening, and how many cycles it survives at an acceptable operating force.
| Comparison point | What to verify | Why it matters |
|---|---|---|
| Security function | Handle-base lock, hook lock, mortise lock or espagnolette gearbox; identify shoot bolts, hooks, keeps, cylinder and frame reinforcement | A keyed handle alone does not provide multipoint security. Forced-entry resistance comes from the compatible lock and its fixing points |
| Keying plan | Keyed-alike, keyed-different or master-key system; keys per unit, duplicate-key supply, key code control and removal in locked and unlocked positions | The wrong plan creates access problems, uncontrolled duplicates or costly rekeying |
| Operating life | Cycle-life test and operating-force figures for the complete assembly, with the door correctly aligned | A handle can pass bench turning tests yet fail when compressed seals, misplaced keeps or sash misalignment increase the load |
Ask for the test basis, sample results and warranty exclusions before approving a lot. Excessive force is frequently an installation or alignment fault, not proof of stronger security; a stiff handle can damage the gearbox and encourage users to force the key.
For wholesale supply, retain an approved sample and match every carton to the same model, key profile, spindle and lock mechanism. Check replacement handles and cylinders before installation, because visually similar units with different keyways or spindle lengths are not interchangeable.
Check Materials, Corrosion Resistance and Installation Requirements
For Mumbai, reject any quote that says only “rust proof”: compare the base metal, coating system and declared corrosion class separately.
| Material | Main risk | What to inspect |
|---|---|---|
| zinc die-cast | Porosity, blistering and coating failure at edges | Unbroken finish around screw holes, spindle openings and key-cylinder bore |
| Aluminium alloy | Pitting and galvanic attack against wet aluminium sections | Compatible fasteners and an isolating layer between dissimilar metals |
| Stainless steel | Grade and surface finish determine resistance | Stated stainless grade, brushed or polished finish, and evidence of staining control |
| Plated steel | Scratches expose steel beneath the plating | Plating thickness or system, sealed edges and protected cut-outs |
Ask for the EN 1670 corrosion-resistance grade, test method, substrate and complete coating system. The commonly quoted benchmarks are about 24, 48, 96, 240 and 480 hours for grades 1 through 5; “anodized” or “powder coated” alone proves little.
ISO 9227 and ASTM B117 salt-spray hours compare laboratory performance, not service life in Mumbai, because they do not reproduce crevice corrosion, installation scratches, pollution deposits or galvanic contact.
Before approving a lot, confirm:
- The aluminium or uPVC profile, door thickness, reinforcement position, lock-box depth, keep and mounting-hole centres.
- Screw type and length, spindle length, cylinder position and required cut-out; a handle can fit the visible opening yet fail to engage the gearbox.
- Coating coverage inside holes and at interfaces, where trapped moisture starts corrosion.
- Compatibility with framed glass or timber sections if those are included in the order; their fixing method is different.
Use a Wholesale Comparison Sheet Before Approving the Lot
Approve a lot only against a written comparison sheet, not the first attractive sample. For a sliding handle with key wholesale in Mumbai purchase, require the supplier to sign the following details before production or dispatch:
1. Attach a retained reference sample with the model code, finish, spindle length, backset, fixing centres and cylinder type. State the permitted finish tolerance; a visually similar handle with a different keyway or spindle is not an acceptable substitute.
2. Record the keying schedule: keyed-alike or keyed-different, number of keys per unit, duplicate-key availability, and whether the key withdraws when the lock is both locked and unlocked. A master-key order also needs a controlled key plan.
3. Specify the replacement allowance as a percentage of the lot and define the remedy for damaged, mixed or short cartons. Require replacement parts, including a replacement cylinder, without forcing you to buy the complete handle.
4. Require carton labelling showing model, finish, quantity, batch number and key code. Match these labels against the retained sample and delivery note before installation.
5. Attach a dimensioned drawing covering closed-position projection, required stile clearance, backset, fixing centres, spindle section and length. This catches handles that foul a screen or fail to engage the hook.
Aruna Techno Industries can be evaluated on this same sheet when comparing hardware suppliers, rather than on catalogue appearance alone. Reject any quote that leaves the lock mechanism, lot-mixing policy or replacement responsibility unstated.
Frequently asked questions
What should a quotation specify for a sliding handle with key?
It should identify whether you are buying a keyed handle only, a complete lock assembly or a handle paired with a separate lock. Confirm whether the handle drives hooks, a mortise bolt, an espagnolette gearbox or another locking component.
Which measurements should you take before ordering keyed sliding handles?
Measure the door or sash thickness, handle height and width, cut-out dimensions, backset, spindle or cylinder interface, fixing-hole centres and available clearance. Compare these measurements with the supplier’s technical drawing.
How can you compare the security and operating performance of keyed handles?
Compare the locking action, number and type of locking points, keying system, cylinder format, anti-drill or anti-pick features, smoothness under load and documented cycle testing. Check that the handle operates the installed lock without binding.
What material and installation details matter for sliding keyed handles?
Check the base material, surface finish, corrosion-resistance treatment, fastener material and suitability for the site environment. Confirm that the lot includes cylinders, escutcheons, screws, keep plates, spacers and installation instructions when required.
