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 Features:

Rackstuds™ make it much easier to mount your gear because they go in from the front and provide you with 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 one hand!

Rackstuds™ are much simpler, faster, safer and very strong.

Features & Benefits

Unlike cage nuts, Rackstuds™ go in from the front which greatly simplifies their installation. Cage nuts can be quite tricky to get in, especially when the rack starts to get populated or the rack is in situ with the side panels installed.

Rackstuds™ can be installed in seconds and are just as easy to remove and reuse. They’re also tool free.


We wanted to ensure that mounting equipment up to 20kg (44lbs) was possible. With a safety factor of three, 60kgs (132lbs) was our target shear strength for one stud.

We exceeded our expectations with independent testing by SGS Labs yielding the following results:

Push In

Pull Out


46 kgs (101 lbs)

92 kgs (202 lbs)

156 kgs (343 lbs)

Rackstuds™ are made from a non-conductive fiber reinforced thermoplastic so they won’t pose an electrical threat to you or your gear.

They are color coded too, so if you drop one they are easy to find and being plastic, they won’t scratch your equipment either!


Rackstuds™ are designed to fit EIA square punched vertical rails with 9.5mm (3/8”) holes. Field trials revealed that the hole is unfortunately not standardized and varies between 9.3mm (0.366”) and 9.8mm (0.385”) so the Rackstuds™ have been engineered to accommodate these variations. The vertical rail thickness can be up to 2.2mm (0.086”) with a recommended maximum equipment faceplate thickness of 4mm (0.157”).
