Arrow BM20 XL 26D IC7 – Frequently Asked Questions

1) What does the Entrance/Dormitory function on the Arrow BM20 actually do at the door?
It is a keyed entry lock with a separate deadbolt operated by the cylinder. The key retracts both bolts, and the inside lever always retracts the latch for free egress. This is the function used on dorm rooms, apartments, and offices where the occupant wants a deadbolt on top of the latch rather than an office lock with no bolt.
2) Do I have to order the Arrow BM20 handed, or can I flip it on site?
Order it as-is. The BM20 is field reversible, and Arrow states the lockset can be re-handed without disassembling the lock case. One part number covers both hands, which is why it works well as a stocked spare across a building.
3) Can I put the Arrow BM20 on a 3-hour fire rated door?
Yes. The BM Series is UL and cUL listed for fire doors up to 3 hours, and both UL and ULC listings are stated for the lock. It also meets ANSI/BHMA A156.13 Series 1000 Operational Grade 1 and A156.41, and is ADA and ICC A117.1 compliant, so it covers the usual spec language on school, hospital, and healthcare openings.
4) Which cylinder options does the Arrow BM20 come in, and what do I do if I run Best SFIC cores?
Four choices: 6-pin conventional cylinder, 6-pin interchangeable core housing less core, 7-pin IC housing less core, or less cylinder entirely. If your facility is standardized on small format interchangeable cores, take the 6-pin or 7-pin IC less-core version to match the pin count of the cores you already stock. Less Cylinder is the pick when your locksmith is supplying a competitive cylinder to an existing master key system.
5) I'm replacing several locks in one building. Can Arrow BM20 locks be keyed alike?
Yes. Keying is a required selection: keyed different (the standard), keyed alike for multiple locks on one key, or none if you chose a less-cylinder option. There is also a key code field if you need them cut to an existing code so the new locks drop into the key system already running in the building. Keyed locks ship with 2 keys.
6) Will the Arrow BM20 latch pick up my existing strike?
The latchbolt throws 1 inch and the lock takes an ANSI strike, either curved lip or straight lip. If the frame already has a standard ANSI mortise strike prep with a 1 inch deep pocket, it will latch. The latch faceplate measures 8 x 1-1/4 inches, so check that against the existing mortise pocket in the door edge before you cut.
7) Should I use a mortise lock like the BM20 or a heavy duty cylindrical lockset?
A mortise lock like the BM20 goes into a machined pocket in the door edge and carries a separate deadbolt alongside the latch, which a standard cylindrical lockset does not. Pick the mortise if the door is already prepped for one, or if you want deadbolt security and Grade 1 operation on a high traffic opening. If the door has a 161 cylindrical bore instead, use an Arrow cylindrical lock rather than cutting a mortise pocket.
8) What finishes does the Arrow BM20 with X lever come in, and will it match other Arrow hardware in the building?
Five finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 625 bright chrome, and 626 satin chrome. All five are available with any of the four cylinder options. The X lever on L rose trim is part of a family Arrow builds to complement its cylindrical locks and exit device trims, so you can carry the same lever look across mixed hardware on one floor.
9) Is the rose trim on the Arrow BM20 through-bolted, and how hard is the install?
The L rose trim is through-bolted, which keeps the two sides aligned and makes the lever harder to pull off the door. Arrow also ships rose trim with self-aligning trim as standard, which cuts the binding you get when the spindle and rose fight each other during install.
