The Simpson CCCQM5.50-SDSG Cross Column Cap is an engineered embedded column cap built for raised pier foundations and structural applications where heavy beams bear on concrete or concrete block columns. Constructed from heavy-gauge 7-gauge steel with a Hot Dip Galvanized (HDG) finish, this connector delivers the high uplift and lateral resistance required to help structures withstand high-wind events. The main channel accommodates a primary floor support beam while integrated stirrups on each side of the channel support intermediate beams at 90 deg. angles, making this cap an essential component in demanding structural framing connections.

Key Features

• Screws are configured to provide high uplift design values
• Certified welds for confidence in strength and loading

• SSTBs spaced to fit standard CMU cells
• Heavy-gauge beam seat and unique Simpson Strong-Tie SSTB anchor bolts provide high uplift and lateral resistance
• Stirrup on each side of the main channel accommodates intermediate support beams at 90 deg. angles
• Hot Dip Galvanized finish for enhanced corrosion resistance
• Made in the United States

Frequently Asked Questions

What type of foundation is the CCCQM5.50-SDSG designed for?

This column cap is engineered specifically for raised pier foundation construction, where heavy beams bear on concrete or concrete block (GFCMU) columns. It is suitable for structural applications requiring high uplift and lateral resistance, such as in high-wind environments.

What are the main channel and side stirrup dimensions of this cap?

The main channel has a width of 5-1/2 in. and a length of 13-1/2 in. Each side stirrup has a width of 5-1/2 in. and a length of 4 in., accommodating intermediate support beams at 90 deg. angles to the primary beam.

What material and finish does the CCCQM5.50-SDSG use, and why does it matter?

The cap is constructed from heavy-gauge 7-gauge steel with a Hot Dip Galvanized (HDG) finish. The HDG finish provides enhanced corrosion resistance, making this connector well suited for outdoor and exposed structural environments where moisture and weathering are concerns.

How does this cap accommodate both primary and intermediate beams?

The main channel accepts the primary floor support beam, while integrated stirrups on each side of the channel support intermediate beams at 90 deg. angles. This cross configuration makes it an essential component for structural framing connections where beams intersect at a column head.
