This lightweight universal binocular tripod adapter cradle holder tray from Hammers is made of a molded polymer frame with soft padding and an easy-to-use wide elastic rubber tie-down strip. It allows you to better enjoy the view using the binocular when it is mounted firmly on a tripod for extended watching. The stable platform greatly reduces image shake and eliminates eye stress and fatigue. This is really helpful for using with laser range finding binoculars for reliable reading on small targets at a distance. Good for use with most mid to full-size binoculars and very quick and easy to mount and detach. There is a 1/4-20 camera thread at the bottom to connect to a quick plate or ball head of camera tripods or window mounts. Measures 7inch wide and 3 1/2inch deep. Rubber tie-down strip is 1 1/4inch wide. Weight of cradle tray: 3.8oz.
