These attractive spring-return tee hinges with a folded door leaf offer some of the best value we've seen in heavy-duty gate hardware. Made from 3mm (just shy of 1/8") thick steel plate, they are zinc plated and finished with a black electrostatic deposition coating. They have a variable tension pin, which is adjusted and fixed with the included lever bar and fixing pin (similar to the way garage doors are counterbalanced). Mounting leaf is 7 1/2" (190mm)high. 8" (200mm) door leaf length. Priced per pair, with matching hex-head lag screws included.
