Cams can be straight or offset offset cams are reversible. The base is where the key or tool is used to rotate the cam, which is what does the latching. A slam latch is rugged and ideal for industrial, agricultural and construction applications.Ī cam lock is a type of latch consisting of a base and a cam. The slam latch derives its name from its ability to slam doors and drawers shut without damaging the latch. Like all latches, a slam latch is a mechanism to hold a door closed. Spring bolt lock (or night latch): A locking mechanism used with a latch boltĪ slam latch uses a spring and is activated by the shutting or slamming of a door.Doesn't need to be fully closed to secure both halves. Frequently used on tool boxes, chests, crates and windows. Draw Latch is a two part latch where one side has an arm that can clasp to the other half, and as it closes the clasp pulls the two parts together.This arrangement prevents the latch bolt from being depressed through the use of a credit card or some other tool, which would lead to unauthorized entry. The strike plate, however, holds the guardbolt in its depressed position: a mechanism within the lockset holds the latch bolt in the projected position. When the door is closed, the latch bolt and guardbolt are retracted together, and the door closes normally, with the latch bolt entering the strike plate. Deadlocking latch bolt ( deadlatch) is an elaboration on the latch bolt which includes a guardbolt to prevent “ shimming” or “jimmying” of the latch bolt.The latch bolt is disengaged (retracted) typically when the user turns the door handle, which via the lockset's mechanism, manually retracts the latch bolt, allowing the door to open. Once the door is fully closed, the bolt automatically extends into the strike plate, holding the door closed. When the door is pushed closed, the angled edge of the latch bolt engages with the lip of the strike plate a spring allows the bolt to retract.
