Rockwood 910RC Narrow Strike Round Corner Adjustable Ball Catch

Reverse of the common setup. The 910RC uses a narrow strike that mounts on the door, with the spring-loaded catch body mortised into the jamb. If your existing catch has the ball unit in the door edge and the strike plate in the frame, this is not a drop-in swap for it, you would be re-prepping both sides.

The strike measures 1-1/16 by 2-1/8 inches, with round corners on the RC version. That is the footprint to rout into the door for the strike side. Round corner strikes are cut with a router, so the corner radius drops straight in without squaring the mortise by chisel.

Yes, and that is the main reason to pick it over a drive-in catch. The 910 has dual adjustment, one for door clearance and one for holding strength, so you can tune it after the door is hung instead of re-prepping the mortise. Useful on doors that move with the season or on a set of openings that were not hung identically.

The Rockwood 910RC is a screw-fastened adjustable ball catch supplied with 4 ea. #6 x 3/4 inch flat head sheet metal screws, with the narrow strike mounted on the door and the catch body in the jamb. The Delaney Drive-In Ball Catch and the Orca Hardware 70DR Series Drive In Ball Catch are drive-in style catches, where the body is driven into a bored hole rather than secured with face screws. That changes the prep: a drive-in body needs a clean bore sized to the catch, while the 910RC body is fastened through its housing. The 910RC also carries dual adjustment for door clearance and holding strength.

The Rockwood 910RC uses a narrow strike measuring 1-1/16 inch by 2-1/8 inch, mounted on the door with the catch in the jamb. If the existing mortise is a radius-corner cutout, the Orca Hardware 70DR Series Drive In Ball Catch With Radius Strike is the catch in the comparable range that ships with a radius strike, so it addresses a rounded-corner pocket directly. Confirm the existing pocket dimensions against the 910RC strike size before deciding, since the strike footprint is what has to land in the prep.

Four #6 x 3/4 inch flat head sheet metal screws ship with it. That covers both the strike and the catch body in a wood door and wood frame. For a hollow metal frame you will want to confirm the jamb accepts the mortise depth and swap to machine screws with a tapped hole, since the supplied fasteners are sheet metal type.

Solid brass, finished in 626 satin chrome. Brass will not rust out in a humid opening the way a plated steel catch can, which is why these show up in institutional and hospitality work. Satin chrome reads as a dull silver, so it matches satin chrome or brushed nickel hinges and levers rather than polished trim.

It is built to ANSI A156.9, type B03017, the auxiliary hardware standard that covers ball catches. If you are writing a hardware schedule or matching a spec line that calls out a B03017 catch, the 910 answers it directly.

A ball catch like the Rockwood 910 holds with a spring-loaded ball riding into a strike, and on this one you set the holding tension yourself. Pick it when the door needs a definite hold and you want to fine tune the pull force. A roller catch is quieter and easier for light traffic, but you cannot dial in the grip. On a pair of doors with no latch, ball catches at the top of each leaf are the usual approach.

The strike is 1-1/16 inches across, which is what makes the narrow version useful on tight edges and slim stiles where a full-width strike would run past the material. Because the strike goes on the door and the catch body goes in the jamb, the deeper mortise lands in the frame rather than in the door edge.

The Rockwood 910RC is built to ANSI A156.9, B03017, which is the auxiliary hardware standard and the type designation a specifier writes against for a ball catch. Peer ball catches in the same function include the Emtek 8802 Door Ball Catch, the Delaney Drive-In Ball Catch, and the Orca Hardware 70DR Series Drive In Ball Catch. Where the submittal names a B03017 designation, the 910RC is the one in that group carrying it, and it is a brass catch.
