O.E.M.s and large door hardware distributors (such as us here at Anderson Lock) enjoy working with the folks at International Door Hardware. Why? Well, the brand’s products are of the highest quality, no doubt, but also because the folks at International Door Hardware don’t engage in “up and down” pricing strategies. Available both online and in-person is our catalog of International Door Hardware products, chief of which is International’s 5050 Extension Flush Bolt.
