When conceived, the aim of Koblenz’s designers was to develop a complete range of precision sliding door gear that was robust enough to perform even in the most arduous conditions and have a minimal aesthetic impact on the surroundings. Components therefore had to be exceptionally strong but also compact, sliding doors, after all, should be unobtrusive and not bump, rock or clatter, which has oft been the traditional experience of sliding door gear.
Koblenz Sliding Door Gear is suitable for use on both Wooden and Glass door leaves and includes the acclaimed designer solution EXTeRUS.
Anodised aluminium (for EXTeRUS, stainless steel) channel provides an ideal material for cost effective track. It is both lightweight and can be extruded to create exceptionally strong profiles. The anodising process creates a self preserving protective coating, highly resistant to corrosion, peeling and cracking which can sometimes be problematic with painted finish types.
Delrin covered wheels offer high tensile strength, impact resistance and outstanding fatigue endurance. Delrin is also resistant to moisture, solvents and many other potentially damaging atmospheric chemicals. Delrin also maintains a natural lubricity at a wide end-use temperature ranges and offers good electrical insulating characteristics. The combined use of materials and design create inherent door stability and resistance to creep or warp.
The range of Koblenz sliding door gear includes solutions for single, double, simultaneous and telescopic sliding doors. Standard sliding door gear solutions are listed under each product part number, however there is a vast range of standard components that can be combined to meet almost any sliding door conundrum.
