The IDEAL Electrical 35-238 30 ft. Auto-Lock Measuring Tape with Magnetic Tip features a magnetic dual-end hook and double-sided blade. The large Rare Earth magnetic end hook allows professionals who work with ferrous metals to take fast and easy one-person measurements. Combined with its oversized numbers, the tape measure provides for precise measurements, markings, and drawings. A true zero feature ensures accurate inside and outside measuring. The dual-end hook is triple-riveted with a bottom blade protector to reinforce the blade tip and provide maximum pull-out length. A built-in shock absorber protects the blade tip. Other features on the tape measure include an impact-absorbing rubber molded case, graduations printed on both sides of the rule, and a nylon-coating on the 1 in. wide hardened steel blade for maximum durability.
