A locker quotation often names the tier configuration but leaves the supplied parts, internal clearances, lock system and installation scope unclear. By checking the compartment layout, component schedule, dimensions, access requirements and site-work costs, you can compare options without treating a product name as a complete specification.
Key takeaways
- Confirm each compartment’s internal dimensions and clear door opening.
- Ask for the locker body, doors, locks, keys and numbering in the quotation.
- Choose Z-tier lockers for hanging space; choose straight tiers for simpler access.
- Get installation scope, site measurements and delivery terms documented in Mumbai.
What 3-Tier, 5-Tier and Z-Tier Actually Mean
CW 3-tier lockers provide three separately lockable compartments in one vertical column, so one column serves three users. Each compartment is suited to compact personal storage such as folded clothing, shoes, bags or work gear; the reduced height limits long-hanging garments.
CW 5-tier lockers divide the same vertical column into five lockable compartments, giving five users individual storage. The smaller openings suit handbags, footwear, uniforms and other compact items, but they offer less room for bulky coats or helmets.
| Arrangement | Users served | Storage provided |
|---|---|---|
| CW 3-tier lockers | 3 per column | Medium-height personal compartments for folded clothing, bags and footwear |
| CW 5-tier lockers | 5 per column | Shorter compartments for compact clothing, shoes and personal items |
| CW Z-tier lockers | 2 per vertical bay | Offset compartments with longer hanging space and less rectangular shelf area |
CW Z-tier lockers use two offset, interlocking compartments in one vertical bay. Each user gets a separate lockable space, but the left- and right-hand compartments are not identical: garments hang diagonally into the adjacent space, which preserves hanging length without increasing locker width.
Count columns, not just tiers, when calculating capacity. A three-column unit of 5-tier lockers serves 15 users; a four-bay Z-tier unit serves eight. Z-tier doors, hooks and locks are handed, so cleaning and replacement take more care than with identical rectangular compartments.
The Components That Should Appear in the Quotation
A complete locker quotation must name every physical component, not simply say “one locker unit.” For CW tier lockers in Mumbai, ask the supplier to identify what arrives assembled, what arrives loose and what the installation price covers.
| Component | 3-tier and 5-tier locker | Z-tier locker |
|---|---|---|
| Carcass | One steel body divided into three or five vertical openings | One steel body with two angled compartments per Z pair |
| Doors | One separately lockable door for each opening | Two angled doors per Z pair, with their opening direction stated |
| Internal fittings | Shelf or divider, coat hook and door-stop arrangement, if included | Angled shelf or divider, coat hook and door-stop arrangement, if included |
| Hardware | Hinges, handle, lock, number plate and fixing hardware | Hinges, handle, lock, number plate and fixing hardware |
| Base and finish | Legs or plinth, end panels, paint system and colour | Legs or plinth, end panels, paint system and colour |
The quotation should also specify the ventilation-hole pattern. Confirm whether holes pass through the doors only or through the locker body as well; ventilation does not replace room-level exhaust.
- State whether anti-topple brackets, wall anchors and floor fixings are included.
- Record master keys, spare keys and replacement-key arrangements.
- Separate locker price from delivery, floor carrying, assembly, anchoring, installation and GST.
- Confirm doorway, lift and stair handling before accepting a fully welded unit. A locker that fits the drawing can still fail to reach the room.
Dimensions, Ventilation and Clearance to Confirm Before Ordering
The measurements that decide fit are the clear compartment opening, overall locker dimensions and the space needed to deliver, anchor and open each door. Do not judge capacity from the advertised external height alone: stiffeners, lock housings, shelves, folded edges and sloping roofs reduce usable space.
| Configuration | Storage consequence | Check before ordering |
|---|---|---|
| CW 3 tier lockers | Three separately lockable openings; taller compartments suit longer garments | Measure clear height for coats, uniforms and helmets |
| CW 5 tier lockers | Five shorter openings; higher user capacity per floor area | Confirm that bags, footwear and folded clothing fit |
| Z-tier lockers | Handed, offset compartments provide hanging space within limited wall length | Check clear width, hook position and cleaning access |
Specify the ventilation-hole pattern and ask whether perforations pass through the door only or through the locker body too. Wet clothing needs airflow, but door vents do not replace a room-level exhaust system.
Record these site measurements before approving the drawing:
- Doorway and lift width and height, including stair turns
- Finished-floor level, skirting, wall flatness and the final anchoring surface
- Sprinklers, pipes and other overhead obstructions
- Wall length, locker depth and side clearance for door opening
- Front clearance for users to stand, change and remove contents
Measure the garment or equipment itself against the clear internal opening. Five-tier compartments suit personal clothing and small uniforms better than long coats or bulky protective equipment; a drawing that fits the wall can still fail at delivery or leave doors unable to open fully.
Choosing the Lock and Tier Count for Your Facility
Choose the locker layout and lock by what users carry, how often they change, and who controls access. Offices usually suit three-tier compartments with cam locks; gyms and changing rooms need five-tier or Z-tier units.
A Z-tier locker is not equivalent to a two-tier locker: two-tier provides two conventional rectangular compartments, while Z-tier provides two angled compartments with different door, shelf, coat-hook and usable-volume geometry.
| Facility | Suitable layout | Practical lock |
|---|---|---|
| Office | CW 3-tier lockers for bags, coats and workwear | Cam lock with numbered keys |
| Gym or changing room | CW 5-tier lockers for compact personal items; Z-tier for hanging garments | Coin-return lock or digital lock |
| Factory | CW 3-tier lockers for uniforms and footwear | Has-and-staple fitting for user-supplied padlocks |
| School | CW 5-tier lockers where each pupil needs a smaller compartment | Cam lock with controlled spare keys |
| Hospital | CW 3-tier lockers for staff uniforms and personal bags | Digital lock or master-key cam lock |
| Large changing room | Z-tier lockers when coat hooks and angled hanging space matter | Coin-return or digital lock |
Do not compare only external height and width. Door stiffeners, lock housings, shelves, folded edges and sloping roofs reduce useful internal height, so confirm the clear compartment opening before choosing CW Z-tier lockers or CW 5-tier lockers.
For CW tier lockers in Mumbai, record doorway and lift sizes, stair turns, finished-floor level, skirting, wall flatness, sprinkler obstructions and the anchoring surface. Ask who holds master keys and how replacement keys are issued; an unplanned key system becomes a maintenance problem.
When the Supply Includes Installation in Mumbai
An installed locker-room package is more than a locker shell delivered to your site. Ask a storage locker supplier in Mumbai to separate locker price, transport, floor carrying, upper-floor handling, assembly, anchoring and GST; fully welded units can fail at a doorway or lift even when their drawing dimensions fit.
| Package | Included work | Your exposure |
|---|---|---|
| Supplied locker shell | The quoted carcass, doors, locks, shelves or dividers, hooks, number plates, legs or plinth and fixing hardware only when listed | You arrange movement, assembly, anchoring and damage checks |
| Complete installed package | Delivery to the agreed location, assembly, levelling, anchoring and adjustment of doors and locks | Confirm access, finished floors and the specified anchoring surface |
| Handover-ready installation | The agreed locker, accessories and fixing work, tested against the purchase order | Record missing parts, transit damage and defects before acceptance |
For CW tier lockers in Mumbai, the site survey must record doorway and lift openings, stair turns, finished-floor level, skirting, wall flatness, sprinkler or pipe obstructions and the final anchoring surface. Cubicle World industries Pvt Ltd can be asked to identify these items separately in the quotation rather than leaving “installation” undefined.
At handover, check every item below:
- Count each door, lock, key or electronic credential against the order.
- Open every door fully and confirm it does not foul an adjacent door, wall or skirting.
- Inspect ventilation holes, coating or laminate damage, shelves, hooks, handles and number plates.
- Confirm the locker is level, stable and anchored at the specified points.
- Test master keys, replacement-key arrangements and electronic override credentials.
- Obtain written responsibility for transit damage, missing keys and defective locks.
