Frequently asked questions

What does an Adams Rite 4900 cost?

This page resolves the 4900 against the current Adams Rite price book, live. Faceplate, backset, handing and finish complete the part number; a bare 4900 already carries the standard faceplate (00), so the picker above asks for the backset, handing and finish.

What is the difference between the Adams Rite 4900 and the 4510?

The 4900 is the heavy-duty deadlatch: a solid brass latchbolt with a 5/8" x 1" x 5/8" throw and a stainless steel Auxiliary Linchpin, against the 4510's all-metal latchbolt with a 1/2" x 1" x 1/2" throw and all-metal auxiliary bolt. Adams Rite also states the 4900 retrofits existing 4510 and discontinued 4700 deadlatch preparations.

What door thickness does the 4900 require?

Adams Rite prints a 1-3/4" minimum door thickness requirement for the 4900.

Which backsets are available on the 4900?

Three printed cylinder backsets: 31/32", 1-1/8" and 1-1/2". Case depth varies by backset.

What comes in the box with a 4900?

The 4900 is individually boxed with a strike plate, both flat and radius faceplates, and mounting screws — flat faceplates can be adjusted in the field for right or left beveled edge doors. Cylinder, paddle and handle are available separately.

What cylinder fits the 4900?

Any standard 1" length, 1-5/32" diameter mortise cylinder with an MS cam, such as the 4036 Mortise Cylinder, or a 4066 Thumbturn — from either or both sides of the door, per the spec sheet.
