Isolator Nut 

Isolator Nut

Isolator nuts isolate the wood shrinkage to each level within the ATS. This segmenting of the movement ensures consistent performance. The isolator nut consists of a heavy hex nut connected to a slotted washer, and is fastened with one screw driven through the slotted washer and bearing plate into the bottom plate. Isolator nuts are required on the bottom plate of the floor(s) above a level where a CTUD is used.

Finish

Nut - none; washer - zinc plated

Installation

  1. Thread the isolator nut onto the threaded rod from the level below until it is snug with the bearing plate, and tighten an additional 1/2 turn.
  2. Align one of the slots in the washer with the smaller hole in the bearing plate so that a screw can pass through both.
  3. Drive #8 x 3" screw (provided) through the washer and bearing plate into the bottom plate. A minimum of 1 1/8" of penetration into the bottom plate is required.
