Crosby BL-O ROLLOX Chain Nest Golden Gate Hook

The Crosby BL-O Style Golden Gate Bullard Hooks feature a ball-bearing swivel connection designed to attach directly to chain using an alloy pin. These hooks are ideal for frequent rotation under load, providing smooth movement and dependable performance in hoisting and lifting applications. Each BL-O hook is equipped with a self-closing Golden Gate® latch—a precision, heavy-duty brass alloy mechanism that locks automatically for secure handling yet can be opened easily with one hand.

Key Features:

Ball-Bearing Swivel Bail: Allows for full rotation under load and connects directly to chain by an alloy pin.

4:1 Design Factor: Meets Crosby’s high safety and durability standards for lifting.

QUIC-CHECK® Indicators: Built-in deformation and angle markers for easy visual inspection.

Corrosion-Resistant Brass Alloy: Ensures smooth operation and long service life.

Self-Closing Gate: Secure automatic latch minimizes downtime and increases operator safety.

Important: The BL-O Series includes multiple gate styles depending on size. PIN-LOK® for smaller hooks and ROLLOX® for mid-range chain sizes.

Gate Type Descriptions:

PIN-LOK®: Stainless-steel pin passes through the gate and engages a notch in the hook shank. Unlocks by moving a small lever—ideal for positive mechanical security.

ROLLOX®: Dual-arm gate with trigger release, allowing quick one-handed operation for applications involving frequent hook access.
