Rockwood 593 Roller Latch with Angle Stop

The 593 mounts in the door header, with the strike installed in the top edge of the door. That is the reverse of a typical edge-mounted roller catch, so there is no mortising into the lock edge or the jamb. The nylon roller rides into the strike as the door closes, holding it shut without a latchbolt or a knob. Body fasteners are 2 each #12 x 1-1/2 inch flat head wood screws, strike fasteners are 2 each #8 x 3/4 inch flat head combo screws, so the head frame needs to take a wood screw of that size.

Two preps. The latch faceplate in the header measures 1-1/2 x 4-1/2 inches, and the strike in the door top measures 1-1/8 x 2-1/4 inches. Lay both out before you cut, since the two parts have to line up across the head of the opening rather than across the lock edge.

It carries ANSI A156.16, L09111. That is the auxiliary hardware standard, and L09111 is the roller latch type designation, which is what an architect or a facility spec writer is looking for on the submittal. The 593 is a commercial-grade item, cast brass body.

No. A roller latch holds a door closed by friction on a nylon roller, and the 593 is an auxiliary catch, not a locking latch. It has no deadlocking latchbolt and no cylinder. Use it on a door you want held shut and quiet, like a closet, a corridor door with no lock, or a pair with an inactive leaf. If the opening needs to be latched or locked, you need a mortise or cylindrical lock instead.

The Rockwood 593 mounts in the header with its strike in the top of the door, so it needs an overhead frame member to work. Where that is not available and the latch has to go in the door edge or the strike jamb instead, the Emtek 8803 Heavy Duty Roller Latch is the edge-style roller catch to specify. Both hold a door closed with a spring-loaded roller rather than a latchbolt, so the closing action feels the same to the user; only the mounting location changes.

No - the two faceplates are different shapes. The Rockwood 593 uses a 1-1/2 inch by 4-1/2 inch latch faceplate, while the Emtek 8803 Heavy Duty Roller Latch is a 7/8 inch by 6 inch unit. The 8803 is narrower and two inches longer, so a pocket routed for the 593 will leave gaps at the sides and come up short at the ends. Treat them as separate preps and cut for whichever one is going in.

It stops the door at the head rather than letting it swing past. The 593 combines the roller hold with a stop in one header-mounted unit, so on an opening where you want the door held closed and its swing limited, you are installing one piece instead of a separate roller catch and a separate stop.

Roller projection adjusts on the 593, so you can dial in how much force it takes to push the door open or pull it closed. That matters on light doors in an office or classroom where a stiff catch fights the closer, and on doors that have sagged or where the head clearance has changed. The roller itself is solid nylon, which keeps it quiet on repeated cycles.

Mounting location and prep. The Rockwood 593 goes in the header with the strike in the door top, which keeps the lock edge clear and works where the door has no lock prep at all. An edge-mounted roller catch such as the Emtek 8803 heavy duty roller latch (7/8 x 6 inches) mortises into the lock edge of the door with the strike in the jamb, the same way a conventional latch does. Choose the header type when the lock stile is occupied or you do not want to cut it, and the edge type when the head has no room or you are matching an existing edge prep.

No, the strike comes with it. The 593 ships as the header body plus the 1-1/8 x 2-1/4 inch strike, with the screws for both: #12 x 1-1/2 inch flat head wood screws for the body and #8 x 3/4 inch flat head combo screws for the strike. Nothing else is required to complete the install beyond the two mortises.

The Rockwood 593 is the one that carries a published ANSI designation - ANSI A156.16, L09111 - and it is a commercial-rated part built from cast brass, which is what a facility spec or submittal package usually needs to reference. The Emtek 8803 Heavy Duty Roller Latch is a roller catch of the same functional family and suits openings where the specification is written around the hardware's function rather than an ANSI reference number.

No roller latch will, and that includes both the Rockwood 593 and the Emtek 8803 Heavy Duty Roller Latch. A roller catch holds a door in the closed position with a nylon or metal roller riding over a strike, and it releases with a straight push or pull - there is no bolt throwing into the frame and nothing to key or lock. On the 593 the roller projection is adjustable, so the holding force can be tuned, but it is still friction holding the door, not a latch engaging it. Where the opening has to secure, specify a latchset or a mortise lock instead.

Two: 613 satin bronze oil-rubbed and 626 satin chrome. If you are matching existing hardware in a building, 626 is the standard match for satin chrome levers and closers, and 613 for dark bronze trim. Pick to match what is already on the openings, since the faceplate shows on the underside of the header.

The body is cast brass with a solid nylon roller, and it is a commercial-rated item to ANSI A156.16. Rockwood hardware of this kind goes into institutional buildings, schools, hotels, detention and sports facilities. For a fleet of doors, the projection adjustment is the useful part: as doors and frames move over time you re-set the roller rather than replace the catch.
