Construction
Well-spaced twin 1-5/8" wheels for exceptionally smooth running action. The wheels feature a hard, abrasion-proof nylon surface which is particularly suitable for soft floor coverings such as carpets. Each caster is rated for 77 lbs (35 kg) load-carrying capacity. The caster swivels freely 360 degrees for easy mobility.

Installation
Each caster is securely attached with an included metal socket fitted over the steel caster stem for press-fitting into a 10 mm hole in the target furniture item.
