C.R. LAURENCE C0L044SC CRL Satin Chrome Cologne 044 Series Wall Mount Offset Back Plate Hinge. CRL Cologne Hinges are similar to the popular Vienna Hinges, but with one change: They have radius corners and beveled edges to provide a sleek appearance. Cologne Hinges are the solution for wider, heavier doors that traditional hinges are not strong enough to support. Two strategically placed steel pins inside the hinge provide template options, and satisfy two schools of thought for mounting shower door hinges. For the safety of "mouse-ears" type cut-outs, the two steel pins should be left in place. This allows the Cologne Hinge to be used with its own CRL "mouse-ears" cut-out. On the other hand, to enable increased adjustability, the two pins can be removed. This allows the Cologne Hinge to fit its own CRL rectangular shaped, square cornered cut-out. In some cases, it will also fit competitive rectangular, square cornered cut-outs..
