Innovation in design, both aesthetic and functional, is what keeps Sun Valley Bronze an inspired and evolving company.

Precision machining and practical engineering ensure our products are of superior quality throughout. Sun Valley Bronze designs for longevity, using only the finest grade bronze for castings and stainless steel for internal mechanisms. All machining is performed on state-of-the-art equipment, capable of meeting tolerances to 1/10,000th of an inch, producing un-compromised quality and lifelong performance.

Careful attention to detail makes our hardware FIELD REVERSIBLE and FIELD SERVICEABLE, setting Sun Valley Bronze apart in the industry. Our entry sets are interchangeable from active to dummy function and feature reversible handing. 

Sun Valley Bronze internal spring assists and limiters are made of the highest quality stainless steel that will not corrode in humid or coastal climates. Teflon-coated for smooth operation, our stainless steel springs are an integral part of the technical advances which ensure that Sun Valley Bronze hardware is built to last. Our revolutionary spring assist is so durable that it outlasted the cycle tester; the tester itself failed at 1.5 million cycles.

This remarkable hinge incorporates innovative design, precision machining, and a stainless steel ball bearing, to create a low-friction, smooth operating hinge that is easily adjusted.

A pair of matched hinge leaves are fitted around an adjustment mechanism and tension pin that allow vertical adjustment of either hinge leaf relative to the second hinge leaf at any time. Partial threading of the mechanism and tension pin prevents over-adjustment, thus protecting the structural integrity of the hinge. The stainless steel ball bearing, fitted between the hinge leaves, reduces friction and extends the useful life of the hinge. The hinge is easy to lift off by simply lifting upward. Long term performance is assured through meticulous design details.
