A Quarter Turn Karabiner secure connector is one of the most important parts of a work-at-height system. It connects harnesses, lanyards, ropes, anchorage devices and other fall-protection equipment, so the locking mechanism and material strength must be suitable for demanding use.

PN111(ME) is a Quarter Turn Karabiner manufactured from high-strength alloy steel for professional height-safety applications. It uses an oval body, a quarter-turn automatic locking nut and a self-closing gate. The gate provides a 16 mm opening, while the manufacturer lists a minimum breaking strength of 25 kN.

The galvanized finish improves corrosion resistance and helps the connector withstand regular industrial handling. Its oval shape also helps keep connected ropes, lanyards and other components correctly aligned during use.

Nassguard supplies the Steel Locking Karabiner across Qatar and Doha for construction, industrial maintenance, rope access, fall protection, rescue and other professional work-at-height requirements.

What is PN111 Quarter Turn Karabiner?

PN111 is an alloy-steel connector designed to provide a secure connection between compatible components in a personal fall-protection system. The main advantage of this model is its quarter-turn locking mechanism. Instead of manually tightening a threaded screw sleeve through several rotations, the locking nut uses a short quarter-turn action. This makes opening and securing the connector quicker during regular use.

The gate is self-closing, helping reduce the chance of leaving the connector open after operation. Once properly closed and locked, the karabiner provides a dependable connection for suitable fall-protection equipment. Its oval profile distributes connected equipment around the central axis and helps ropes, lanyards and devices remain aligned. This makes the Safety Locking Karabiner useful across several professional height-safety systems.
