Rackstuds are the revolutionary replacement for cage nuts which are used to mount IT, Pro, A/V, Security and Telecommunications equipment in 19" racks. Rackstuds make it much easier to mount your gear because they go in from the front and provide you a place to support your equipment while you spin on the lock nut. This makes inserting and removing Rackstuds much quicker and assists with mounting even heavy equipment as it no longer needs to be balanced in on hand.
