More about this product

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. Available in 0.020", 0.030" and 0.040" thicknesses for the following applications:

0.020" use for under 3" tube diameters and small baffle tubes

0.030" use for 3" to 8" tube inside diameter

0.040" use for tubes larger than 8" inside diameter

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, or in larger rolls at a discounted price. Installation instructions and tips included. One cut length per order please. 10" minimum order quantity. Made in the USA.
