Finish – Bright zinc plating
Top plate and fork base are hot forged steel that has been induction hardened to ensure uniform depth of hardness in the swivel races
Fork legs are 1/4" thick, 2" wide formed steel, with inside and outside welds for extra strength
Wheel axle – 1/2" dia. axle, with lock nut
Fork leg spacing - 2 1/2" width

Series 90-91 casters are made from forged steel. Top plate and inner raceway are forged from one piece, providing a superior raceway construction for shock conditions. This forged design outperforms the standard steel plate welded to tubular steel inner races, especially in abusive and impact-loading conditions
