WEJ-IT® Drop-In Anchors
With Or Without Lip
WEJ-IT® MINI Drop-In Anchors
Ideal for hollow core, precast, and post tension slabs
WEJ-IT® POWER-Drop® Drop-In Anchors are "internally threaded wedge anchors".  
It has a safety shoulder that supports the clip when the anchor is under strain, eliminating bolt-end collapse and / or clip slippage under
ultimate loading conditions.  It is 'seismic rated', whereby its allowable values may be increased 33-1/3% for short term loading in
resisting earthquake or wind loads.
