Product Description
The TOPTEK TKAMDL2000 is a commercial single-cylinder deadbolt with an outside key cylinder and an inside thumbturn. It provides a keyed outside locking point while allowing the inside user to project and retract the bolt by turning the knob.
Choose this configuration when the door schedule calls for an outside key cylinder and a manually operated inside thumbturn. The inside control is the defining difference from the TKAMDL2200 double-cylinder model. Browse the commercial deadbolt lock range to compare the four cylinder arrangements.
Key Features
- Outside key control with inside thumbturn operation
The outside cylinder and inside thumbturn operate the deadbolt. This gives the two sides different controls without adding a second keyed cylinder. - One-piece protective housing
The catalogue describes a thick-walled, one-piece housing that supports the lock cylinder and reduces the need to mate a separate outer shroud and inner base. - Adjustable-backset latch selection
The family offers a 60/70 mm adjustable deadbolt latch. Confirm the selected backset, faceplate and strike against the actual door and frame preparation. - Latch and strike-component options
The catalogue shows an SS304 adjustable latch and 6-way adjustable latch versions in high-strength carbon steel or stainless steel. Coordinate the latch version, reinforcement plate, strike and strike box with the order. - Cylinder specification for the selected model
Specify the outside cylinder keyway, keying plan and tailpiece arrangement with the order.
