dormakaba Roller Bolt 2520 - Satin Nickel Pearl
The dormakaba Roller Bolt 2520 (DO2520SNP) is a compact mortice roller bolt for cupboard, joinery, pivot and light-duty internal doors. A nylon roller with brass guides gives a smooth, quiet closing action, and the adjustable holding force lets you balance easy opening against a door that stays shut.
It suits doors that need to stay closed without a conventional latch mechanism. For a heavier-duty, fire-rated secondary latch look at the dormakaba RB111 Heavy Duty Roller Bolt, or compare the range in roller bolts for smart locks.

Dimensions
Measure the door edge before ordering - door thickness needs to comfortably take a 22mm wide face plate and a 50mm deep pocket. Checking existing hardware helps when replacing an old catch.
Frequently Asked Questions
It is commonly used on cupboard doors, pivot doors and light-duty internal doors - anywhere a roller catch is preferred to a conventional latch.
Yes. The roller tension can be adjusted to suit the closing force you want. Set it during installation so the door opens easily but still stays shut.
It is typically used where a roller catch is preferred instead of a conventional latch mechanism. If the door needs a handle-operated or lockable latch, a latch or mortice latch is the better fit.
The 2520 has a nylon roller with brass guides, adjustable holding force and a compact 75 x 22mm face plate - it is built for cupboards, pivot doors and light internal doors. The RB111 is the heavy-duty option: stainless steel roller, adjustable strike position, timber or aluminium doors, and fire rated to AS1530 Part 4 as a secondary latching device alongside a primary lock such as the MS2602.
It is a mortice fitting, so the door edge is cut to take the 50mm deep body and let in the face plate, and the strike is fitted to the frame. That suits a confident DIYer or a joiner - when DIY makes sense - and we can help with installation if you prefer.
Additional Information
Roller bolts provide a smooth, quiet closing action compared to spring latches.
They are often specified where doors do not require positive latching but still need to remain closed. Latch vs bolt explains the difference between latching and bolting hardware.
Adjustment should be set during installation to balance ease of opening with secure closure. Door misalignment is the most common reason a roller will not catch the strike.
The dormakaba RB111 is the heavy-duty, fire-rated choice, and the Lockwood 7580 roller bolt in matt black suits darker hardware. Browse all smart lock accessories.
For commercial fit-outs or a mix of doors across a site, book a site survey and we will match the hardware to each door.
