The Core-Lock system Drain Blocks are designed to promote proper water drainage within Core-Lock base shoe systems. Installed inside the base shoe channel, these blocks help maintain a drainage path beneath the glass, reducing water accumulation and supporting long-term system performance. Available in three sizes to accommodate different Core-Lock base shoe series, they are suitable for both indoor and outdoor railing applications.
