The BLAX adapter simply screws onto the top of any spade or buzz bar, instantly transforming it into a "Quick Release" system. Both the loss-proof wing screw and the adapter are fully compatible with the 2-in-1 key, and the inner cylindrical shape allows for quick and easy alignment of the sensors with the rods. Made from 300 series stainless steel and lightweight 6063 aluminum used in aerospace. Black anodized finish designed for long durability. Winged, loss-proof screws. Thread diameter: 3/8 BSF - suitable for all spades and buzzer bars. Compatible with the 2-in-1 key.
