Applying an ultra-black lining to your telescope tube has never been easier. FlockBoard (Patent pending) is our light trap surface manufactured onto a low-density plastic sheet. Simply roll it up, and let it snap out against the tube wall. It stays in place without glue or tape. FlockBoard cuts easily with scissors or a utility knife, and also drills cleanly. Small screw holes can also be poked through cleanly using just a pointed tool.

FlockBoard is ordered cut-to-length from the roll (24" width), or in larger rolls at a discounted price. Installation instructions and tips included. One cut length per order please. 15" minimum order quantity. Thickness: 0.040". Made in the USA.

NEW! We now offer pre-cut FlockBoard sheets for 2' x 2', and 2' x 4' drop ceilings (see the order table below). These can be used in home theater applications, or other uses where it's necessary to reduce room brightness. These veneer panels simply slip between the rails and your existing drop ceiling panel...no adhesives or tapes required. Self-adhesive light trap tape (1-5/8" width) is available for covering the metal support rails.
