3M Company 2835-B Duct Tape 1.88 in X 35 Yd Extreme Hold

Product Description

The 3M COMPANY 2835-B is a heavy-duty duct tape engineered for extreme-hold applications in demanding trade environments. Measuring 1.88 inches wide by 35 yards long, this tape features a double-thick adhesive layer bonded to a strong woven scrim backing. The waterproof backing resists moisture, making it well-suited for use in wet or humid conditions. HVAC technicians, plumbers, and general contractors reach for this tape when standard-duty options fall short on rough, irregular, or contaminated surfaces.

This tape is designed for heavy-duty sealing, bundling, and repair tasks where maximum holding strength is required. Typical applications include temporary duct patching, pipe insulation securing, weatherproofing wrap jobs, and structural bundling on job sites. The woven scrim construction resists tearing during application and holds under tension, making it practical for overhead and hard-to-access installs where repositioning is not an option.

Key Features

• Double-thick adhesive layer provides extreme holding strength on demanding surfaces
• Strong woven scrim backing resists tearing and holds under sustained tension
• Waterproof backing resists moisture exposure in wet or humid environments
• 1.88-inch width and 35-yard length suited for extended runs without mid-roll changeovers
• Aggressive adhesive bonds to rough, irregular, or lightly contaminated surfaces

Compatibility

Designed as a general-purpose extreme-hold duct tape for use across HVAC, plumbing, electrical, and construction trade applications where a high-strength, moisture-resistant tape is required.

Installation Notes

Clean and dry the application surface before applying for best adhesion. Apply firm pressure along the full length of the tape to ensure full contact with the substrate. For HVAC ductwork applications, verify that the tape meets any applicable local code or energy code requirements for duct sealing, as pressure-sensitive tape may not substitute for mastic or listed duct sealant in all jurisdictions. Cut with a utility knife or sharp shears for a clean edge.
