Ojmar Hasp Locks for Locker Doors
Ojmar padlock hasp locks convert compatible lockers to user-managed padlock access. They can be specified for new lockers or considered when replacing worn, keyed or coin-operated locking systems on otherwise serviceable locker doors.
The chrome-finished hasp is intended for use with a suitably sized padlock. Ojmar offers mounting arrangements for different door materials, with an optional backplate to address certain existing OTS or coin-lock footprints. Matching the existing door preparation is essential before ordering.
Padlock Access Without Individual Locker Keys
A hasp allows the locker user to secure the door with a compatible keyed or combination padlock. For sites that currently issue individual locker keys, this can reduce the administration involved in managing a key for every locker. The site must still have a policy for lost padlocks, abandoned lockers and authorised access.
The lock has a built-in anti-rotation arrangement and is designed for frequent use in communal locker installations. Security also depends on the selected padlock, locker construction and correct fitting.
Converting Compatible Coin Lockers to Padlock Use
Some existing locker doors can be converted from a coin or electronic lock to a padlock hasp without replacing the whole door. Ojmar offers the 039.002PN backplate for compatible OTS and coin-lock footprints. The plate is an accessory, not a universal conversion kit.
A successful conversion requires checking the opening, fixing positions, lock handing and rear cam engagement against the actual locker door. Do not assume that every Euro-style coin-lock installation accepts the same hasp or backplate.
Compare the listed purchasing options and the fitting requirements before modifying the door.
Choosing the Correct Hasp, Mounting and Padlock
Before ordering, identify the lock already fitted, the locker-door material and thickness, and whether it is left- or right-opening. Check that the replacement cam will engage the frame correctly and that the mounting method matches the door.
The manufacturer's hasp accepts a padlock shackle up to 8 mm in diameter. The maximum figure is not a guarantee that every padlock of that size will suit the door or provide sufficient clearance. Review the padlock body, shackle dimensions and locker design.
Ojmar's catalogue lists the backplate under manufacturer reference 039.002PN. The second TLS purchase option is described as a hasp lock with backplate; confirm its exact supplied contents if a complete conversion assembly is required.
Applications for Ojmar Padlock Hasp Locks
Suitable installations may include leisure-centre changing rooms, gyms, schools, staff facilities and commercial locker banks. Ojmar describes the hasp as resistant to moisture for wet-area locker applications. This does not by itself establish suitability for unprotected outdoor use.
Refurbishment can be economical when the existing locker bodies and doors remain in good condition. Where hinges, frames or cam engagement are damaged, those faults should be assessed alongside the lock change.
Help Identifying an Ojmar Hasp Conversion
For a replacement or conversion enquiry, send the existing lock reference, photographs of the front and rear of the locker door, the fixing aperture, and the quantity needed. Use our locker part identification service, call 01284 749211 or email sales@totallocker.co.uk.

Ojmar Hasp Purchasing Options Listed by TLS
| TLS product code | Listed description | Selection guidance |
|---|---|---|
| O039.0X0045CR | Hasp lock H-00 R-45, screw mounting | Check the existing aperture, screw fixing, door handing and rear cam engagement |
| O039.002PN | Hasp lock with backplate for Euro fitting (TLS listing) | Confirm the supplied assembly before ordering: 039.002PN is the manufacturer's backplate accessory reference |
These are the current TLS listing identifiers, not a claim that both references are complete manufacturer hasp assemblies. The optional backplate and the hasp mechanism should not be assumed interchangeable. Product descriptions, packaging and the selected item's supplied contents should be confirmed against the corresponding stock record.
Fitting and Coin-Lock Conversion Checks
The appropriate mounting method depends on the lock version and locker material. Ojmar documents nut mounting and screw mounting, with dedicated drawings for left- and right-hand arrangements. Use those drawings to check hole positions, rear clearance and cam engagement rather than relying on the appearance of the existing lock face.
| Existing locking system | Record the lock type, manufacturer and any stamped reference |
|---|---|
| Door preparation | Measure the existing aperture and fixing-hole positions against the manufacturer drawings |
| Door thickness | Confirm the locker door does not exceed the specified 20 mm maximum |
| Mounting and handing | Check the selected nut/screw mounting and left/right orientation |
| Rear cam | Check cam shape, position and clearance against the door frame |
| Optional backplate | Compare the old OTS/coin-lock footprint and confirm whether the plate is included |
| Padlock | Check shackle diameter (maximum 8 mm), reach and body clearance |
For full measurements and fitting sequences, consult the Ojmar hasp technical drawing and assembly instructions. Check that the instructions relate to the actual fitting supplied.
Ojmar Hasp Lock FAQs
What size padlock fits an Ojmar hasp lock?
Ojmar specifies a maximum padlock shackle diameter of 8 mm. Check the shackle's usable height and the padlock body's clearance on the actual locker door before ordering.
What is the maximum locker door thickness?
The manufacturer specifies locker doors up to 20 mm thick. Also confirm the fixing aperture and rear cam clearance, since door thickness alone does not establish compatibility.
Can an Ojmar hasp replace a coin-operated locker lock?
Some compatible coin-lock installations can be converted. Ojmar offers an optional backplate for selected OTS and coin-lock footprints, but the original door opening, fixings and locking cam must be checked first.
What is the Ojmar 039.002PN backplate?
039.002PN is Ojmar's reference for an optional backplate intended for compatible OTS and coin-lock footprints. The TLS purchase option using this reference is described as a hasp with backplate; confirm the supplied contents if you need a complete conversion assembly.
Do these hasp locks work on left- and right-opening locker doors?
Ojmar manufactures left- and right-hand arrangements. Confirm the handing and fixing of the selected item before purchasing rather than assuming the same assembled lock suits every door.
Are Ojmar hasp locks suitable for wet changing rooms?
Ojmar specifies the range for humid locker environments and lists moisture resistance. Confirm the intended cleaning conditions and exposure before choosing a lock for a particular wet-area installation.
Is a padlock supplied with the Ojmar hasp?
A padlock should not be assumed to be included. Check the specific product's supplied items or quotation and see the Total Locker Service padlock range for compatible options.
What is the difference between nut and screw mounting?
Ojmar provides different mounting arrangements to suit the door and hasp version, including nut-fixed and screw-fixed designs. Compare the existing door preparation with the manufacturer drawing before selecting a replacement.
Do I have to replace the locker door to fit a new hasp?
Not necessarily. If the existing door, fixing aperture and cam engagement are compatible and in sound condition, replacing the lock may be sufficient. For uncertain fittings, supply photographs and measurements before ordering.
