• Parallelism tolerance of rial end face: ±10 arc minutes；
• Outer wings form a dovetail mounting surface;
• Eight M6 threaded holes are provided on both ends;
• Four Ø3.0 mm alignment holes are provided for locating pins on both ends;
• Black anodized coating.

     The OMDQ-B series is similar to the OMDQ-A series, but the former features a higher angle tolerance, which makes it applicable for sensitive experimental equipment. Two paralleled T-grooves are provided with an interval of 46.0 mm on each side of the rails. With these features, standard optomechanical elements can be directly mounted onto the rails through rail carriages, rail plates and T-nuts. Eight M6 threaded holes provided on the wings are compatible with our leveling feet and base plates. They are all designed to connect rails with each other, or locate rail assemblies on a flat surface. Four additional Ø3.0 mm holes are arranged on each wing of the precision rails to connect the rails to OMDK95B 95 mm horizontal mounting rail clamps or alignment pins of custom devices.

• Minimum footprint for 95 mm 1-axis construction rails;
• The 50.8 mm long clearance grooves are equipped for mounting the rails onto optical tables;
• The cutting grooves are designed to provide two connection lines;
• Surface subject to clear anodized finish.

     The OMDR-A series 95 mm one-sided construction rails provided by OMTOOLS have the same mounting surface with the standard four-sided rails. Each side of the rails is designed with several 50.8 mm long clearance grooves, for which M6 cap screws can be used. The cutting grooves at the bottom enables firm mounting of rails onto the mounting surfaces. Such a compact and multipurpose design makes it easier to mount OMDK-A series components onto optical tables or breadboards. The OMDR-A series is provided with a durable clear anodized surface.
