Middle Atlantic 5WL Locking Caster for Slim 5 Rack Bases
Overview
The Middle Atlantic 5WL is a single locking caster designed for Middle Atlantic Slim 5 series rack bases. The locking mechanism lets you roll a loaded rack into position and lock it in place — eliminating the hazard of rack drift in server rooms, AV equipment bays, or mobile staging environments. At 1,300 lbs (589.7 kg) rated capacity per set, the 5WL handles fully loaded rack enclosures without flex or creep. The MPN is 5WL; this listing covers a quantity of one caster.
Compatibility
The 5WL is engineered specifically for Middle Atlantic Slim 5 series rack bases. If you are building or replacing casters on a Middle Atlantic rack base outside the Slim 5 product family, verify base series compatibility before ordering — Middle Atlantic produces multiple base platform lines and caster fitment is not universal across series. For full base and accessory selection, reference the rack base accessories catalog to confirm your specific base model accepts 5WL casters.
Installation Notes
Dimensions are 4.38 in (W) × 3.88 in (H) × 3.13 in (D). Confirm these clearances against your rack base mounting pockets and floor-to-base height requirements before installation — adding casters raises the overall rack height by approximately 3.88 in, which matters in low-ceiling or under-desk deployments. The locking style means each caster has an independent locking brake; engage all casters before loading equipment to prevent uneven floor stress.
