Merco Tape® M333 Electrical Tape ~ All Weather-All Temperature and Flame Retardant ~ U/L Black in cannister

Merco Tape^® M333 is our high quality M307 U/L listed, all weather electrical offered in a reusable plastic canister (yeah, just like 3M). The tape is ideal for most any demanding application (and the canister is handy for your stash when the tape is done.)

Why pay for 3Ms when you only need one?

Merco Tape's M 333 is a Black U.L and C.S.A. approved All Weather-All Temperature electrical that offers super elasticity and highly conformable with excellent insulating properties. It resists abrasion, corrosion, moisture, alkalis and acids and varying weather conditions. It is also UV resistant.

Merco Tape^® M 333 is ideally suited for moisture tight electrical and mechanical connections. Merco Tape^® M 333 offers a working temperature range down to -12C (for UL standards) and -18C (for CSA standards) and is suitable for temperatures as high as 105C.

Merco Tape^® M 333 also meets the requirements for MIL A-A-55089 (which has superseded MIL I-HH-595.)

We only offer our M 333 in full length 66' rolls, not 60' like some other manufacturers. Don't need the canister? See our M 307 electrical. Need colors? See our M809. Both are excellent tapes and are used by many utilities and cable companies throughout the country. They don't want to pay for 3Ms either.
