dormakaba RB111 Heavy Duty Roller Bolt - Stainless Steel - Fire Rated
The dormakaba RB111 Heavy Duty Roller Bolt (BORB111SC) is a secondary latching device for commercial and residential doors. It pairs a stainless steel roller with a satin chrome pearl housing, and a fully adjustable strike position lets it cope with varying door-to-frame gaps on both timber and aluminium doors and frames.
The RB111 is fire rated to AS1530 Part 4 as a secondary latching device. It holds the door closed alongside a separately fire-rated primary lock such as the dormakaba MS2602 Primary Mortice Lock, and it is a common companion to the dormakaba M5 BLE smart lock on fire door installs.
Usually ships same day if ordered before 11am AEST (excludes weekends and Queensland public holidays).
The RB111 is fire rated in accordance with AS1530 Part 4 for use as a secondary latching device. On a fire door it always works alongside a separately fire-rated primary mortice lock, which carries the primary lock requirement of the doorset. The rating applies within a certified fire door assembly - see how lock fire testing works and the one-penetration principle before adding hardware to an existing fire door.

Suitable Uses
- Secondary latching device on fire-rated door assemblies where a fire-rated primary lock is also installed - browse our fire door smart locks.
- Timber and aluminium commercial doors requiring a supplementary catch.
- Doors where the door gap varies and a fixed-strike roller bolt would not engage reliably.
- Internal and cupboard doors requiring a light latching action without a key-operated lock.
- Fire door smart lock installations that need a secondary latch - for example alongside the dormakaba M5 BLE Smart Lock and MS2602 mortice lock.
Use on its own as the only hardware on a door - the RB111 must always be paired with a primary lock, including on fire doors. Doors that need resistance to forced entry - a roller bolt holds the door by spring pressure only, so fit a key-operated primary lock, or choose a deadlatch where a secondary device must resist back-pressure.

Frequently Asked Questions
A fire door assembly needs a primary lock, and many also carry a secondary latch. The RB111 has been tested to AS1530 Part 4 in the secondary latch role - it helps hold the door closed during a fire alongside a separately certified primary lock. It cannot be the only latching or locking device on a fire door: a fire-rated primary mortice lock such as the dormakaba MS2602 must also be fitted. Our article on primary and secondary locks explains the rules.
The strike plate fixing slots are elongated, so the strike can sit closer to or further from the door edge to suit the gap on site. If the gap is too wide the roller will not compress and engage the strike; too narrow and the door will not close fully. Set the strike depth during installation before fixing - door misalignment is the usual reason a roller or latch will not catch.
No. A roller bolt is a passive spring-loaded catch - it holds the door closed by spring tension against the strike, but gives no resistance to someone deliberately pushing or pulling the door open. Fit it alongside a key-operated primary lock on any door that needs security.
Yes. The RB111 suits both timber and aluminium doors and frames. On aluminium frames use self-tapping screws rated for the frame material, and if in doubt ask your frame manufacturer or talk to us about installation.
Yes, provided the smart lock and the RB111 are both fire rated and the overall door assembly is certified. The smart lock provides the primary locking function and the RB111 the secondary latch - the dormakaba M5 BLE on an MS2602 mortice is a typical pairing. Adding hardware to a certified fire door can affect its certification, so confirm with your fire door specialist first. See Chapter 05 - Fire Door Smart Locks.
Additional Information
On certified fire doors the one-penetration principle generally allows only one lock body penetration under the fire test certification. Adding a secondary device outside the terms of the certified doorset may affect compliance, so confirm with the door manufacturer or a fire door specialist before fitting the RB111 to an existing fire door. Secondary locks and the one-penetration principle covers what is and is not permitted, and how to identify a fire door helps if you are unsure what you have.
A roller bolt holds the door closed by spring pressure alone - the roller compresses as the door closes and springs into the strike, with no deadlocking action. A deadlatch has an automatic deadlocking latch bolt that resists back-pressure. For external doors, or anywhere forced-entry resistance matters, a deadlatch is the better secondary device. The RB111 suits internal doors, controlled-access commercial doors and fire door assemblies where the primary lock provides the security. Latch vs bolt explains the difference.
The RB111 is certified to AS1530 Part 4, the Australian standard for fire-resistance testing of building elements. Fire doorsets themselves are certified under AS1905 Part 1 - Chapter 11 explains that standard in plain English, and our fire rating certificates reference page covers test reports.
For cupboards, pivot doors and light-duty internal doors the dormakaba 2520 roller bolt (nylon roller, adjustable holding force) is a lighter alternative, and the Lockwood 7580 roller bolt in matt black suits darker hardware schemes. Compare them in roller bolts for smart locks or browse all smart lock accessories.
Fire door and strata work should go to a licensed installer who can confirm the doorset certification before any hardware is added. When DIY makes sense covers simpler internal doors, and we can book a site survey for commercial and apartment installs.
