This two piece weld-on hinge is extremely popular because of its high weight capacity as well as its professional appearance. Ideal for gates, machinery doors, barbecue pits, electrical boxes, and trailers. It can be welded on as a lift-off hinge or it can be permanently mounted. Made from mild steel (1015) with a case hardened fixed steel pin and a brass washer. Also known as a cigar hinge. Installation Weight rating should be used only as a general guide. Load compensation should be made when determining the size and number of hinges for applications that may be subject to dynamic forces (shock loads), areas where the pin is set in a horizontal position, and other uses that create extra pin stress (ie. long gates, wide doors, etc.) The addition of heat-resistant molybdenum or lithium based greases to the hinge's internal body before final assembly is recommended and may provide freer movement and a longer life. No guarantee is made for weight loads and dimensions. 2" Model Dimensions: 2" Length, 5/16" Diameter 3/16" Pin Diameter 150 lb per pair weight rating The diameter plus the welding area (S-Dimension) is 3/8". 3" Model Dimensions: 3-3/16" Length, 1/2" Diameter 5/16" Pin Diameter 300 lb per pair weight rating The diameter plus the welding area (S-Dimension) is 5/8". 4" Model Dimensions: 4" Length, 5/8" Diameter 13/32" Pin Diameter 440 lb per pair weight rating The diameter plus the welding area (S-Dimension) is 25/32". 6" Model Dimensions: 6" Length, 3/4" Diameter 1/2" Pin Diameter 650 lb per pair weight rating The diameter plus the welding area (S-Dimension) is 1". 8" Model Dimensions: 8" Length, 27/32" Diameter 5/8" Pin Diameter 850 lb per pair weight rating The diameter plus the welding area (S-Dimension) is 1-3/32".
