The pipe hinge is part of our pintle system of gate hinges. This product will work with a screw pintle, bolt pintle or upright pintle. All are sold separately. When ordering the other part of this hinge make sure that the pintle sizes match. For example, if you order a Pipe Mounted Pintle Hinge with a 5/8" pintle make sure the other component has a 5/8" pintle size also. There are two models; one model fits a 1-5/8" diameter pipe and the other model fits a 2" diameter pipe (dimensions listed are actual outside diameter measurements of pipe or tubing). The weight ratings listed are for one hinge. For example, if the listed weight rating is 70lbs for one hinge and you use two hinges then your combined hinge installation would be rated at 140lbs. Note: When ordering Pintle Hinge System components, please note that listed sizes, like a 3/4" pintle diameter, are nominal, not exact dimensions. Utilize our nominal sizes to match straps and pintles seamlessly. If you're attempting to match our products with items you already own based on pintle diameter or other dimensions, be aware that doing so is at your own risk due to potential slight variations in manufacturing measurements. Ensure precise matching by using our integrated ordering system to guarantee compatibility and fit. 5/8" Pintle Pipe Size: 1-5/8" Weight Rating: 70 lb per hinge 3/4" Pintle Pipe Size: 2" Weight Rating: 125 lb per hinge
