Screw-Gate Carabiners
Classic strength and versatility: Screw-Gate Carabiners
Screw-gate carabiners are the classic workhorse of climbing and rescue. At The Outdoor Warehouse, we stock lightweight aluminum screw-gates for multipitch climbs and heavy-duty steel NFPA-rated models for rope rescue, arborist, and rope access professionals. Their manual locking sleeves give climbers and rescuers complete control in any situation.
Also called locking carabiners, manual lock biners, twist-sleeve carabiners, and NFPA rescue carabiners.
Why Choose Screw-Gate Carabiners
- Versatility: Ideal for anchors, belay setups, and general climbing use.
- Control: Manual locking sleeve ensures deliberate closure.
- Strength: Available in lightweight aluminum or steel for rescue-rated strength.
- NFPA Options: Many steel models meet NFPA “G” General Use standards.
Understanding Screw-Gate Carabiners
Screw-gate carabiners are a staple in every climber’s rack. By twisting the sleeve manually, the gate is secured against accidental opening. They’re perfect for anchors, belay devices, and multipitch climbing, where reliability and deliberate control matter most.
- Aluminum Screw-Gates: Lightweight and compact, ideal for climbers who count every gram.
- Steel Screw-Gates: Heavy-duty, abrasion-resistant, and common in rescue, fire service, and arborist work.
- Pear/HMS Shape: Widest gate opening, best for belaying with tubes or Munter hitches.
- D-Shape: Higher strength-to-weight ratio, excellent for anchors and hauling.

Screw-Gate Carabiner Checklist

- ✔ Choose steel for rescue or arborist use, aluminum for climbing efficiency.
- ✔ Look for NFPA/CE/UIAA markings where compliance matters.
Pro Tip
Carry a mix of auto-lock and screw-gate carabiners. Use screw-gates for anchors where deliberate security matters, and auto-locks for belaying where speed and safety are critical.
Seasonal Reminder
Before big climbing trips or rescue season, check your screw sleeves for grit or stiffness. Clean and lubricate lightly to keep them reliable in the field.
