Baldwin Reserve 8BR0311004 UL Round Corner Adjustable Springlatch

One latch covers both. The 8BR0311004 is an adjustable springlatch that sets to either a 2-3/8 inch or a 2-3/4 inch backset, so it drops into either of the two standard residential bore preps without ordering a second part. Measure from the door edge to the center of the cross bore to confirm which setting you need before installing.

Round corner. The 8BR0311004 springlatch uses a 1 inch by 2-1/4 inch round corner faceplate, which matches a door edge mortise cut with a router and template rather than a chiseled square pocket. If the existing latch in your door has square corners, this one will not sit flush in that mortise without recutting the corners.

Yes. The 8BR0311004 is UL certified for a 20 minute rating, so it can be used in a 20 minute fire rated opening. It is not carried with any higher rating, so for a 45, 60, or 90 minute door you need a latch listed for that duration.

Yes, the 8BR0311004 is sold as a replacement part on its own, so a failed springlatch in a Baldwin Reserve knob or lever set can be swapped without buying a whole new lockset. Confirm the existing door edge mortise is round corner at 1 inch by 2-1/4 inches and that your cross bore sits at 2-3/8 or 2-3/4 inches from the edge, and this latch goes back into the same prep.

It is a springlatch, meaning the bolt is beveled and spring loaded so it retracts when the door closes against the strike and is thrown back by the knob or lever. That is the latch used behind passage, privacy, and keyed knob or lever sets in the Baldwin Reserve line. It is not a deadbolt latch, so if you are replacing the bolt in a deadbolt housing this is the wrong part.

Residential. Baldwin catalogues the Reserve 8BR0311004 springlatch for residential service, so it suits homes, apartments, and multi-family unit doors rather than high-traffic commercial openings. For an office, school, or retail entrance with heavy daily cycling, specify a commercial grade latch and lockset instead.

A springlatch bolt is beveled on one side, so it has to face the direction the door closes. The 8BR0311004 is not sold as separate left and right parts, so the bevel is reversed at installation by rotating the latch bolt rather than by ordering a hand. Check the bevel points toward the stop before you drive the faceplate screws.

Brass. The 8BR0311004 springlatch is a brass latch, supplied in a 004 satin nickel finish so the exposed faceplate on the door edge matches satin nickel Reserve trim. Only satin nickel is offered on this latch.
