## Description

This is a large, extremely handy, 4" long, rounded, double sided perf board. Standard 0.1" spacing with a 4-40 (3mm) holes for mounting. The neat thing about this board is the group of three holes per pad. One hole is 39mil, large enough for regular 22AWG wire. The other two holes are electrically connected to the main hole but are smaller 24mil diameter and work with our 30AWG wire wrap wire.

**Note:** Color my vary. They can be either green or red.
