Lindapter Alphawedges are intended to fit into the dovetail slots of Richard Lees decks, Alphalok, or Ribdeck AL decking to provide a secure point with guaranteed loads for suspending building services. The wedge nut and locking plate are pre-assembled on the threaded rod before being inserted into the slot and rotated 90°. Tightening the nut against the locking plate secures the unit in place. Alphalok Plate is included. Suitable for Ribdeck E60.
