Model F-CC Cable Clamp is a convenient, general-purpose device that securely holds fiber cables and provides strain relief. The fiber can be clamped in place in either of two V-grooves. The two clamping bars can mount on an SP Series Support Post at any convenient height. They lock in place with a knurled thumbscrew. For direct mounting to tables, positioners and post holders, a stub post with a threaded stud is also provided. The stub post can also be used to hold a cable in the outer V-groove when the clamp is post-mounted. The V-groove arrangement makes this clamp useful as a laboratory holder for small cylindrical optical elements as well as optical and electrical cables.
