Calbrite S45800PBSQ is a 304 stainless steel square post base designed for a 1-5/8" channel/strut system, engineered to accept a 1-5/8" square post for secure floor mounting. The post base is fabricated from SS304 stainless steel and features a welded strut foot that integrates with the channel framing to provide a rigid foundation for vertical posts used in railing, signage, or equipment-support installations. Its square footprint and stainless construction are intended to deliver durable, corrosion-resistant performance in commercial and industrial framing projects that require a stable, long-lasting post support. As part of Calbrite's post base family, it is compatible with standard 1-5/8" strut channels, helping ensure straightforward installation and reliable long-term strength.
