Deltana RCS338 Roller Catch Surface Mounted

The RCS338 is a light-duty roller catch meant for cabinet doors and similar lightweight closet doors. It holds a door closed by friction on a spring-loaded roller, so it won't hold a heavy solid-core passage door reliably. For a standard entry or passage opening you want a latching device with a bolt and strike, not a friction catch.

No mortising. The RCS338 is surface mounted, so it screws onto the face of the cabinet frame or door with no router work and no drilled pocket. That's the practical difference from a mortise roller catch, which needs a bored or chiselled recess in the door edge. If you're retrofitting an existing cabinet or closet door with no prep, surface mount is the one that goes on without cutting the door.

The Emtek 8801 Roller Catch is the closest cross-brand equivalent ZenSupply carries. Pick between them on finish match to the rest of the door hardware in the room, since both do the same job. The Deltana RCS338 is the one to specify if you need a surface mounted catch in solid brass.

Mounting hardware is in the bag. Each RCS338 ships in an individual poly bag with its mounting hardware, and it's sold each, so one unit covers one door. Order per leaf if you have a pair of cabinet or closet doors.

Solid brass, both the body and substrate. That matters where the catch lives in a humid room, a bath vanity or a coastal property, since brass won't rust the way a plated steel catch will once the coating wears at the roller.

Deltana lists the RCS338 as a commercial grade item, and it's solid brass rather than a stamped consumer catch. That said, its duty is still light: cabinet and lightweight closet doors. Commercial here means the finish and material hold up in a hotel, office or multi-family casework application, not that it will restrain a heavy door.

That's exactly the case a roller catch suits. The RCS338 mounts on the surface and catches a strike that also mounts on the surface, so neither the door nor the frame needs a bored latch hole or a mortised strike pocket. On older casework or closet doors where you don't want to cut anything, this goes on with screws alone.
