4mm ID Aluminum Spacer (8mm OD, 43mm Length) - 4 Pack

This 43mm Length, 4mm ID Aluminum Spacer is a lightweight structural solution that can slip over an M4 screw to create space between components. In comparison to the 6mm OD of a 1502 Series Spacer, the 8mm OD of this spacer creates a larger footprint for greater stability.

The 43mm length of this spacer allows it to fit just right within 1120 and 1121 Series U-Channel and provide rigidity to your structure.
