The MT-OWR1 Lock Ring Wrench provided by LBTEK is specifically designed for adjusting the lock rings of MT-AM1S5 stainless steel mirror mounts. It features a dual-wrench-head design, allowing the lock ring adjustment and the threaded pair to be aligned in the same line. The Ø3 mm through-hole at the center of the wrench head enables a 2 mm hex key to pass through the wrench, facilitating simultaneous adjustment of the threaded pair while adjusting the lock ring.

LBTEK 0.5-inch stainless steel mirror mount, equipped with two vertical drive adjusters with locking rings, for mounting 12.7 mm Optical Components. Suitable for situations where space behind the mount is limited and horizontal adjusters cannot be used. The Optical Components are locked by flexible spring tabs and set screws. Two knobless M4×0.20 precision adjusters (with locking rings) provide ±4° angular adjustment and are operated with a hex wrench.
      The MT-AM05S5 mounting holes are two M4 countersunk holes; the MT-AM05S5A has one M4 threaded hole and one M4 countersunk hole. The front and rear plate connecting block of the MT-AM05S5A is made of 316L stainless steel (the MT-AM05S5 is made of copper), which provides better corrosion resistance and outgassing characteristics, and the adjustment feel is more convenient for fine adjustments. The adjuster ends have a stop structure to prevent the locking rings from being unscrewed and falling off.
