Blue Fireball's heavy duty Binocular-to-Tripod L Adapter is perfect for mounting any size binocular with 1/4-20 threading to a 1/4-20 tripod head found on photo and telescope tripods. The L-bracket is made of black anodized aluminum (unlike the cheaper plastic ones you may see on the market).
It features two mounting holes (spaced 16mm / 0.63" apart) so that you can adjust the position of the bracket/binocular on your tripod for better balancing. The height of the adapter is approximately 108mm / 4.25" and the length of the shorter horizontal base is 49mm / 1.93".
The width of this adapter is 1.18" (30 mm), so please ensure that the intra-ocular distance of your binoculars is greater than this when you use them.
