Product catalog summary
ESP Pulley Materials
ESP pulleys are designed with a durable protective finish. The sheaves and sideplates are Hardkote-anodized for enhanced strength and durability, and they are UV-stabilized with a black additive for maximum protection. The surface is Teflon®-impregnated to ensure smooth operation.
ESP Swivels and Fiddles
These components are suitable for purchase systems with a ratio of 4:1 or less. A set screw in the three-way head allows the shackle to be locked in front or side positions or to swivel, preventing line twisting.
Hexaratchet® Materials
Hexaratchet® pulleys feature Hardkote-anodized, Teflon®-impregnated sheaves made from solid aluminum, providing strength and corrosion resistance. Delrin® ball bearings and UV-stabilized components with carbon black ensure maximum protection. Stainless steel straps reinforce the pulleys.
ESP Pulleys
These pulleys are simple in design, featuring sleeve bearings to handle high static loads.
Midrange Hexaratchets®
These pulleys have a side switch to engage or disengage the ratchet mechanism.
