Product details
The 227 has a parabolic profile rather than a conventional D shape. It is made from sheet alloy steel, heat treated, 100% proof loaded to 3600 lbs (16 kN), and rated at a minimum breaking load of 5000 lbs (22.2 kN).
A parabolic curve tends to let a snap hook or carabiner settle at the apex of the ring, keeping the load centred. Designers use this shape on harness dorsal positions, lanyard and strap ends, and positioning belts where they want predictable connector seating. The flat sheet construction keeps the profile low against the webbing.
Dimensions and finish are not stated for this model, so request a drawing and specify the webbing width, plating and any marking in the RFQ, along with the harness standard the finished product must meet. OEM and private-label supply of the 227 is possible, as are modifications made to a customer drawing.
