CRL Aluminum Drain Block for B5S Base Shoe – 10/Pk (BSDB38)
The Drain Block is an essential accessory for any exterior glass railing installation. Manufactured with a durable satin anodized aluminum finish, this drain block is designed to be placed under an exterior-installed base shoe to create the drainage space needed for proper water run-off.
This is especially important for installations on balconies, decks, and other outdoor surfaces, where standing water can dam up around the base shoe if adequate drainage is not provided. Left unaddressed, water pooling can lead to premature corrosion, staining, and long-term damage to both the base shoe and the surrounding structure.
Installation is simple and effective: one Drain Block should be placed under each mounting hole along the length of the base shoe. The blocks can also be rotated to accommodate different base shoe widths, giving installers flexibility across various GRS base shoe profiles.
