We are excited to introduce four more additions to the new 2026 lineup:

Mammoth Corner Bracket

Designed specifically to support an exterior corner post and two intersecting outside rim joists for decks and pergolas, the Mammoth Corner Bracket delivers exceptional structural reinforcement at one of the most critical load points of a deck and pergola. Manufactured from 1/8” structural steel and finished in our durable SandTex black powder coating, this bracket offers superior corrosion resistance and long-term performance.

Mammoth Stair Bracket

Our new Stair Bracket is purpose-built to securely fasten deck stair stringers to the outer rim joist or support beam of any deck. Engineered to be fastened with structural screws tied through the rim joist and into the stair stringer, this bracket provides a strong, code-conscious connection that improves safety and simplifies installation. Constructed from 1/8” structural steel and finished with our SandTex black powder coat, it is designed to perform in demanding outdoor environments.

Mammoth Flat Plate Joiner

The Mammoth Flat Plate Joiner is a versatile solution for joining two outer rim joists or support beams. Ideal for applications requiring added rigidity and alignment, this bracket is fabricated from 1/8” structural steel and protected with our signature SandTex black powder-coated finish for maximum durability.

Mammoth T-Bracket

Engineered to support a center exterior post carrying two outside support beams, the Mammoth T-Bracket provides reliable load transfer and structural integrity where it matters most. Made from 1/8” structural steel and finished in our SandTex black powder coating, this bracket is built for strength, longevity, and professional-grade installations.
