Segmented Slips: Ideal for irregularly shaped or fragile fish, providing multi-point contact to enhance gripping force.
Ring-Type Slips: Suitable for regularly shaped fish, providing uniform contact for stable gripping and less chance of damaging the fish.

Non-releasable Design: Ensures the fish will not be accidentally dropped.
Suitable for Coiled Tubing and Workover Operations: Compact structure adapts to complex downhole environments.
High-Strength Alloy Steel Construction: Wear-resistant, and can withstand high temperatures and high pressures.
