Pamex DD05-100 Round Corner Strike for Ball Catch

The ball catch bores into the top edge of the door at 7/8 inch diameter, 1-1/8 inch deep, and the bullet itself is 1 inch diameter where it protrudes. Drill the 7/8 inch hole in the door edge and mortise the round corner strike into the head jamb opposite it.

The strike is a full lip plate measuring 1-3/8 x 2-1/4 inches with round corners. Round corner means it drops into a jamb prepped by a router template rather than a square-chiseled mortise, so it matches the corner radius most modern prehung and factory-machined frames already carry.

A ball catch holds a door shut by spring pressure at the top edge with no latch, no bolt, and no knob action, so the door pushes open and pulls shut. Use it on closet, pantry, and dummy-trim doors where you want a clean edge and no strike hardware at handle height. If the door needs to be held by a lever or knob, or needs any privacy or keying, you want a passage or privacy latch set instead. Ball catches are a residential-duty item and not the choice for a high-traffic commercial opening.

Yes, and it is the usual way to do it. Each leaf gets its own 7/8 inch bore in the top edge with a strike in the head, so the two doors are held independently and neither needs a center latch or mullion. On an inactive leaf paired with a flush bolt, the ball catch keeps the leaf from rattling.

Two screws are included for mounting the strike. Nothing else is needed to hang it, the catch body is a friction fit in the 7/8 inch bore.

Six finishes, by BHMA number: 605 bright brass, 609 antique brass, 613 oil rubbed bronze, 619 satin nickel, 622 matte black, and 625 polished chrome. Because the strike sits in the head jamb and the bullet in the door edge, most of the hardware is out of sight, so matching the door's hinges or lever finish is usually the deciding factor rather than an exact match to anything else in the room.

Depends on the stile and rail. The catch needs 1-1/8 inches of solid depth in the top edge to seat the body. A hollow core door with a solid top rail takes it, one with a thin cardboard-core top rail does not. Check the top rail before you drill.

Not without rework. The DD05-100 ships with a 1-3/8 x 2-1/4 inch round corner strike, which leaves a gap at each corner if you drop it into a square-chiseled mortise. Either square the strike's corners with a file or chisel the mortise corners round to match.
