This oval set of back door hardware features both a lever on the outside and a lever on the inside and is applicable to both left and right. The security hardware is spring loaded and has a profile cylinder hole size of 72 mm and is manufactured from stainless steel. By using solid stainless steel this product has a long life and the brushed treatment gives the product a matte look. The security hardware is equipped with key pull protection, which protects the cylinder from being pulled out and drilled into the cylinder core. Core pull protection has been mandatory in new construction since the end of 2013 and for existing construction since April 2014. The security hardware is SKG*** approved, which means that it is extra heavy burglary resistant hardware.
