Product details

The Intermatic 21T156A is a 3 inch standoff spacer, sold four to a pack. It is the genuine Intermatic part from the pool and spa controls hardware line.

What it does

A standoff spacer separates two parts of an assembly by a fixed distance. The spacer sits between them so the mounted component stands off its backing rather than resting flat on it, holding the gap the assembly was designed around.

Ordering

Each pack contains four spacers, which covers a normal four corner mounting job. Check the length you need before ordering, since this listing is the 3 inch size only.
