In Focus: Lock Technology Self-Locking Door Wedge

June 3, 2014
This door wedge allows for easy entry and positioning between the door and rubber strip during body work.

The Lock Technology LT276 Self Locking Door Wedge has a wash board/wave ripple surface to it, allowing for easy entry and positioning between the door and rubber strip. The rippled wave-like surface securely locks the wedge in place making it almost impossible to slide out. This tool makes a great addition to a technician's lock out tool kits, and is also a great aid when completing window regulator replacement to hold glass securely in position during use

Features and benefits

This door wedge incorporates a “washboard wave ripple” design to eliminate slippage once inserted in a door or window frame between weather strippers.


  •     Use this door wedge to insert lockout tools through the door rubber stripper area.
  •     Use to aid in inserting inflatable air bags in door frames.
  •     Very useful for holding door glass in place during window regulator work.


The technician who came up with this design was frustrated with current door wedges on the market. They were all flat and triangular in shape, which tended to slide out during use.
