No39 Universal Hinge SS316 100 x 70 x 2.5mm - Stainless Steel

The Universal Stainless Steel Hinge (MPN: No39 / SKU: 1304180) is a premium, marine-grade architectural security hinge manufactured by ASSA ABLOY / Lockwood and distributed via Alspec. It is specifically engineered to mount high-performance aluminium security screen doors and barrier doors. Forged from genuine 316 Marine Grade Stainless Steel, the hinge offers extreme resistance against harsh atmospheric pitting, making it well suited to coastal and high-salinity environments. It has been salt spray tested to in excess of 1,000 hours without degradation and is finished with a Stainless Steel Electropolished surface for enhanced smoothness and shine. The hinge features a specialised step-over, offset contour profile, where the door leaf layer sits cleanly over the outer lip on the edge of the aluminium door stile. This creates an anti-pry interlocking seam that reinforces the frame perimeter against forced entry. The hinge stands 75mm high, with an overall open leaf width of 45mm, a material leaf thickness of 1.6mm, and a 6mm profile knuckle/step gap. This standard version (LW545SS / Alspec Code 1304180) represents the base security hinge layout. A Safety Prong Version is also available (LW546SS / Alspec Code 1304193), featuring an integrated mechanical interlocking stud — if an intruder forcibly cuts or grinds away the external hinge pin, the internal safety prong keeps the door captive and locked within the framing track.
