The Simpson Strong-Tie ECCQ77SDS2.5 is a heavy-duty end column cap engineered to deliver reliable column-to-beam connections in wood construction end-of-beam applications. Fabricated from 3-gauge steel with a Simpson Strong-Tie Gray paint finish, this column cap features an extended seat design that increases the bearing surface area beyond the column's side face, helping to distribute beam loads more effectively across the connection. Supplied with 28 Strong-Drive SDS Heavy-Duty Connector screws, the ECCQ77SDS2.5 offers faster installation and engages a greater net section area of the column compared to traditional bolt attachments.
