Weslock 0090542--0020 Mesa Knob Half Dummy Lock

Product Description

The WESLOCK 0090542--0020 is a half dummy knob lock in a Matte Black finish, designed for interior door applications where a functioning latch or lock mechanism is not required. The Mesa knob style provides a clean, consistent look that pairs with matching active hardware sets. At 0.9 pounds, this lightweight trim piece installs without complex tooling and is suited for closet doors, double door setups, and any passage point where a stationary knob is needed for appearance rather than security. Concealed installation screws give the finished installation a cleaner look than exposed-fastener alternatives.

Half dummy locks are typically used on single-sided or double-sided non-latching doors such as closets, pantries, French doors, and bifold entry points. The Matte Black finish suits modern, transitional, and industrial interior design styles. This unit ships as a single piece, making it straightforward to order exact quantities for multi-door projects or to match an existing hardware installation.

Installation Notes

Half dummy knobs are installed by finish carpenters, general contractors, or experienced DIYers and do not require a licensed trade. No door boring or latch prep is needed for dummy function — confirm the door is pre-drilled to the correct cross-bore diameter before installation. Fasten according to the manufacturer-included hardware to ensure the concealed-screw trim plate seats flush. Verify the knob style and finish match any active hardware on adjacent doors before ordering.
