THL-VHH900 - Top Insert for Fiber Holding Blocks, Clearance Slot for Large-Diameter Fiber

• Select the Top Inserts that Match Your Bottom V-Groove Inserts Selected Above (See Table to the Right)
• Two Required: One Each for Left and Right Fiber Holding Blocks

In addition to the bottom V-groove inserts that must be installed in the FHB1 non-rotating fiber holding blocks, top inserts must be purchased as well. There are two choices of top inserts. The THL-VHH000 is a flat insert that fits in the lid of one of the fiber holding blocks; it is compatible with all of our bottom V-Groove inserts except the THL-VHH900S. If you are using the THL-VHH900S as a bottom V-groove insert, you must select the THL-VHH900 as the top insert to allow clearance for the lid of the holding block to close.
