Rockwood 590 Roller Latch with Cast Strike

A roller latch holds a door closed by friction, not by a latchbolt. The Rockwood 590 has a solid nylon roller in a cast brass body that rides over a cast strike, so the door pushes open from either side with no knob or lever action and no keying. That makes it right for closet doors, dummy or push/pull leaves, and inactive doors on a pair where you want the leaf to stay shut but not be locked. If the opening has to latch positively, resist a pull, or carry a fire label, a roller latch is the wrong part and you want a mortise or cylindrical latch instead.

Cut the door edge for a 1 x 3-3/8 inch faceplate and the frame for a 1-11/16 x 2-1/4 inch strike. Both parts mortise flush and fasten with two #8 x 3/4 inch flat head combo screws each, which are supplied. Since the roller projection adjusts, you can dial in the fit after the prep is cut rather than having to hit the gap exactly.

It is built to ANSI A156.16, function L09091, which is the auxiliary hardware standard covering roller latches. That is the number to put on a submittal or a hardware schedule when a spec calls for a roller latch by function. The 590 is a commercial-grade part.

No. A roller latch has no latchbolt, so it cannot provide the positive latching a fire door assembly requires. Use it on closets, inactive leaves, and other non-labeled openings, and specify a labeled mortise or cylindrical latch where the door carries a fire rating.

The Emtek 8803 Heavy Duty Roller Latch is the closest peer. Both are roller catches that hold a door closed with a spring-loaded roller rather than a latch bolt, so either works on an inactive leaf, a closet, or a door with no lockset. The difference is the mortise footprint: the Rockwood 590 has a 1 inch by 3-3/8 inch latch faceplate with a 1-11/16 inch by 2-1/4 inch strike, while the Emtek 8803 is a 7/8 inch by 6 inch unit. The 590 is cast brass and carries ANSI A156.16, L09091.

No. The Rockwood 590 latch faceplate measures 1 inch by 3-3/8 inch, and the Emtek 8803 Heavy Duty Roller Latch measures 7/8 inch by 6 inch. The Emtek body is nearly twice as long, so replacing a 590 with an 8803 means lengthening the edge mortise and cutting a new faceplate pocket. Going the other direction, a 590 will not cover an existing 6 inch prep. For a like-for-like swap in an existing 590 opening, order the 590; the body mounts with 2 each #8 x 3/4 inch flat head combo screws and the strike with the same.

That is exactly the job. The 590's roller projection adjusts, so you back it out to take up a loose gap and hold the door tight against the stop, or run it in if the door is hard to push open. The nylon roller means the adjustment stays quiet, with no metal-on-metal click each time the leaf swings. What it will not do is secure the door; there is no bolt, so anyone can push it open.

Four finishes: 625 bright chrome, 626 satin chrome, 612 satin bronze, and 613 satin bronze oil-rubbed. Those are standard BHMA finish numbers, so 626 matches satin chrome levers and hinges across the building and 613 matches oil-rubbed bronze trim. Both the body and the cast strike are brass under the finish.

No. The 590 ships as a set with a cast strike, and both the body and the strike come with their own mounting screws, two #8 x 3/4 inch flat head combo screws apiece. Nothing else is required to hang it beyond cutting the two mortises.

No handing. The roller is symmetrical and rides over the strike from either direction, so one part works on a left hand or right hand door, inswing or outswing. Pick the finish and you are done; there is no LH/RH suffix to specify on the 590.

Both hold a door shut with a spring-loaded roller, but they are prepped differently. The 590 is an edge-mortised latch: a 1 x 3-3/8 inch faceplate in the door edge against a 1-11/16 x 2-1/4 inch cast strike in the frame, built to ANSI A156.16 for commercial work. The Emtek 8803 is a heavy duty roller catch measuring 7/8 x 6 inches, a different footprint that will not drop into a mortise cut for the 590. If you are matching an existing prep, cut for the one you are actually buying.

The Rockwood 590 is the one to specify when the drawing calls out a standard. It is a commercial-duty roller latch in cast brass and carries ANSI A156.16, L09091, which is the auxiliary hardware designation a facility spec or submittal will typically reference. The Emtek 8803 Heavy Duty Roller Latch is a roller catch in a 7/8 inch by 6 inch size and is the choice when the opening needs the longer body rather than a rated callout.

The 590 is a commercial part with a cast brass body and strike, and the roller itself is solid nylon rather than a hollow or plated piece, so the wear surface does not flatten or squeak the way cheaper catches do. Rockwood hardware of this type goes into institutional buildings, schools, healthcare, hotels, and detention work. For standardizing a facility, the ANSI A156.16 L09091 function number is what you put on the schedule so every opening gets the same part.
