Projector mounting spacer

This is a mount for my projector to the mounting bracket. it's an m4 hole, and spaced to fit within the rails.

The mount I have is "VIVO Black Universal Adjustable Wall Ceiling Projector Mount Bracket Extendable Length Projection" , part number MOUNT-VP06B

My projector is a SHARP PG-D40W3D.

it does require longer M4 bolts (25mm if I remember off the top of my head), and washers from the mount were reused.
