Kendrick ZAPCAPS are constructed of the same black ABS plastic as Dewcaps, are all felt lined and are attached by wrapping it around your telescope just below the lens or corrector plate ring. The two outside ends are then pressed together using the sewn on Velcro. The ZAPCAPS have a
built in low wattage heater that makes good contact with your telescope to keep it free of moisture. The heater is inside a rubberized sleeve and it is this sleeve that provides a friction fit and keeps the ZapCap in place.
Has had Some minor trimming to allow for bottom bar on telescope.
