So I decided to rack mount as much of my gear as I could with the aim of making my music room as neat as possible an minimising the amount of "trip hazard" on the floor as my long suffering wife has the ability to trip up on her own shadow :)
I wanted to fit a few Adam Hall 87556 sliding rails to the excellent Thon 20U Studio I was purchasing. The sliding rails need mounting at the rear as well as the front so this rack strip was purchased.
After carefully measuring the required front-rear distance my sliding rails required I marked the rack itself, made some pilot holes and fitted the strip with the screws provided.
The fitted nuts make mounting equipment at the space you want (rather than the rack forcing you to use specific spacing) is excellent. I normally use a small Philips screwdriver.
