Amazon link for casters - https://a.co/d/hkM3n4O **Plate 1 is a straight mount version for the original rails. These will require you to drill 8mm or 5/16 diameter holes thru the aluminum corner rails for bolts. **Plate 2 is designed not only for the upgraded Alpha rails with pre drilled and tapped holes, but are also angled slightly outwards and tipped down. This makes for a slightly more stable caster location and makes the caster pivot plate level to they rotate more evenly and roll nicer. Both require eight bolts, nylon lock nuts and washers in M5 x 40 for the casters. The plate 1 original will need four 8mm x 45mm SHCS and nylon nuts for mounting to the rails. I would even suggest getting 70mm long ones and go all the way thru the bars and into the case with nuts and washers inside. Just to make it easier for removal if you ever ha
