AU741 / AU741DS Series features a e-coated hardened steel lock body with molybdenum shackle to resist drilling, sawing, twisting and brute force attacks. The rectangular design limits the spacing and blocks the access to blot cutter when the lock is in place. The anti-drill sliding cover plate provides high standard drilling resistance in cooperation with slide-in slot and anti-drill plate.

Both single and double slot options are available and can be used in accordance with chains or hasps.
