The FH-1S Filter Holder is designed to securely mount 1.0 inch (25.4mm) round filters in a three-sided, spring-loaded, v-groove clamp and still allow for quick and easy interchange of the optic. Simply squeeze on the lower portion of the spring-loaded Delrin arm and insert the filter. When the arm is released, the filter will be held firmly in place. The FH-1S Filter Holder incorporates a counter bored clearance hole in its base, compatible with both 8-32 and M4 Screws, allowing for post mounting on English and Metric SP and MSP Series Posts, as well as PS Series Pedestal Posts. And, like the FH-R series, the FH-1S has two sets of threaded and clearance holes on the face of its base for use in stacking.
