Polarizer Rotation Mount, A-LINE, 25.4 mm Diameter, M4 Thread

The A-LINE™ M-LH-1PR Polarizer Rotation Mount can be used with the rest of the A-Line™ Self-Aligning mounts to create a complex optical system. The rotator holds 1-in.

The front of the holder also has a special 6-mm alignment hole, which can be used with LH-GR Series Guide Rods for fast alignment of several A-LINE™ lens mounts. The LH-1PR incorporates an M4 threaded mounting hole for post mounting on Metric M-SP and TSP Series posts.
