Omega Technologies ATBRO2528 Hi-Lok 1/4” x 9/32” Offset Box Ratchet with collar-stops for Hi-Lok® and Hi-Lite® collars from Omega Technologies are made of high quality, heat-treated steel and finished with a nickel-chrome plating. The result is a durable, long-lasting tool. Small size and variable shape make the box ratchet ideal for use in tight areas. Even without line of sight, the head fits easily onto a collar, while the shoulder ring prevents the collar from slipping though the socket.
