The simple, low-profile design of these fixed casters not only allows them to be mounted easily and unobtrusively, but their compact footprint also permits installation in locations that are too restrictive for other caster styles. In addition to their primary use, they can also serve as rollers on workshop guides.
Each caster has a non-marring polymer tire and affixes easily with two screws (not included). The 25mm (1") caster requires #6 screws, the 30mm (1 1/4") caster requires #10 screws, the two larger casters require #12 screws. Wheel diameters and load capacities stated. Made in Germany.
