Deltana FLSP335 Full Lip Strike Plate for Ball Catch and Roller Catch

The plate measures 2-1/4 x 1-5/8 inches with a 1/2 inch lip extension. Those two numbers decide the job: the 2-1/4 x 1-5/8 footprint has to cover the mortise you already have in the frame, and the 1/2 inch lip has to clear the stop and reach the door face so the ball or roller rides up onto it instead of catching the edge. Measure your existing plate before you swap.

Often, yes. A worn or dished lip lets the ball slip out under a slight breeze or air pressure, and a plate that sits proud of the frame keeps the door from closing all the way. A fresh solid brass full lip strike gives the ball a clean seat again. Two things to check before you order: that your existing mortise is inside 2-1/4 x 1-5/8 inches, and that a 1/2 inch lip is enough to reach the door face across your stop. If the ball catch body itself is loose in the door edge, the plate won't cure that.

No. The FLSP335 is a full lip strike plate made for ball catches and roller catches, with a 1/2 inch lip extension and a 2-1/4 inch by 1-5/8 inch face in solid brass. A deadbolt strike such as the Emtek 83223 standard deadbolt strike plate with square corners is a deadbolt strike plate by function, cut to receive a thrown bolt rather than to let a spring-loaded ball or roller ride over a lip and seat. If the door is held by a ball catch or roller catch, the full lip strike is the matching part; a deadbolt strike belongs on a bored deadbolt opening.

The Deltana FLSP335 is the commercial-rated match: a solid brass full lip strike built for ball catches and roller catches, 2-1/4 inch by 1-5/8 inch with a 1/2 inch lip extension. The other strikes commonly stocked alongside it are deadbolt strike plates by function, including the Kwikset 80318 full round adjustable strike, the Kwikset 81640 strike box and the Emtek 83223 deadbolt strike plate with square corners, and none of those present the lip a roller catch needs to ride over. Match the strike to the catch, not to the door.

Solid brass. That matters for two reasons on a catch strike: the lip takes repeated wear from the ball or roller and won't rust out, and a solid brass plate can be dressed or filed slightly at the lip if the door needs a little more or less bite. Deltana rates it for commercial use.

Ten finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If you're matching a building's existing Deltana ball catches across a run of doors, the PVD polished brass is the one that holds its color under handling; the plain polished brass will patina. Paint Black is the option to specify when the frames are painted out.

Go full lip when the catch is at the top of a door and the ball has to climb onto the plate as the door swings shut. The 1/2 inch lip on the FLSP335 gives the ball a ramp and keeps it from chewing the frame edge. A flat, lipless plate only works where the catch meets the plate square on, typically a floor-mounted or head-mounted application with no offset. If your existing plate has a bent lip on it, replace it with a lipped one.

No. The FLSP335 is a 2-1/4 x 1-5/8 inch lipped catch strike cut for a small ball or roller catch mortise. An ASA prep is a different, taller cutout for a latch and takes an ASA plate, such as the Codelocks ASA strike plate in stainless. Don't try to make one cover the other; you'll be filling frame.

The Deltana FLSP335 is a fixed full lip strike in solid brass sized 2-1/4 inch by 1-5/8 inch with a 1/2 inch lip, so its catch position is set by where the plate is mortised. When the alignment has to be corrected at the strike itself on a bolt opening, the Kwikset 80318 full round adjustable strike and the Kwikset 81825 6 way adjustable deadlatch are the adjustable deadbolt strike plate parts in the set. Note those two serve bolt and latch openings, not ball or roller catches.

They are different parts. The FLSP335 is the visible full lip strike plate in solid brass, 2-1/4 inch by 1-5/8 inch with a 1/2 inch lip, that the ball or roller rides against. A strike box such as the Kwikset 81640 strike box or the Kwikset 81231-001 metal strike dust box is a deadbolt strike plate part that lines the mortise pocket behind the plate on a bolt opening. On a ball catch or roller catch installation the full lip strike is what the catch bears on.

The Deltana FLSP335 is solid brass and comes in ten finishes including PVD polished brass, polished nickel, brushed nickel, antique nickel, polished chrome, brushed chrome, oil rubbed bronze and paint black, so a plated look close to stainless is available on the brass body. Where the part itself needs to be stainless, the Codelocks ASA strike plate is offered in a stainless steel finish, though it is an ASA series strike for a latch opening rather than a full lip strike for ball and roller catches.

Sold individually, each. Handy when you're replacing a single damaged plate on one opening rather than buying a whole catch set, and it means you can order a mixed count of finishes across a building without breaking packs.

Deltana lists the FLSP335 as commercial, and it's solid brass rather than plated stamping, which is what carries it through repeat cycles on an office or hospitality door. Common use is a pair of doors where the inactive leaf is held by a ball catch at the head, or a closet and utility door in a managed property where you want the same plate across every opening.
