4" Polypropylene Rigid Caster - 7760s -4

About This Caster - 7760S-4

Set this 4-inch black polypropylene rigid on a fixed corner of a light cart in a wet or wash-down area.

The hard polypropylene wheel wipes clean and shrugs off moisture and cleaning chemicals, which suits the 400 Series role on dollies and stock carts that see spills. As a rigid caster it tracks straight rather than swiveling, so set on the fixed corners it steadies a cart behind a pair of swivels. It is light and economical, with the trade that a hard wheel transmits bumps instead of cushioning them, runs louder than rubber, and black poly can mark a light floor. It runs on a plain bearing, bolts on a 2-15/16 by 4-1/8-inch zinc top plate, and holds from -20 to 180°F.

Ideal applications

• 4-inch polypropylene rigid on a light wash-down cart
• Straight-tracking fixed corner on a 2-15/16 by 4-1/8 plate

For more ground clearance, the 5-inch 7760S-5 steps up to a taller wheel.

Pairs with: matching 400 Series poly swivels on the steering corners and this rigid on the fixed corners.
