5/8" x 4" Concrete Dowel Caps

Allows Smooth Concrete Joint Movement While Protecting Dowel Bars

The Sandbaggy 5/8" x 4" Plastic Dowel Cap allows concrete slabs to expand and contract properly while maintaining effective load transfer across expansion joints. Installed on one end of a 5/8" smooth dowel bar, it creates the void space needed to reduce cracking and joint stress.

Made from heavy-duty, corrosion-resistant plastic, these dowel caps are durable, easy to install, and ideal for sidewalks, roadways, warehouse floors, parking lots, and other slab-on-grade concrete applications.

FAQs

Do I install a cap on both ends of the dowel bar?

No. Typically, a dowel cap is installed on only one end of the dowel bar to allow controlled movement at the expansion joint.

Will these rust over time?

No. They are manufactured from corrosion-resistant plastic and will not rust like metal components.

What size dowel bars are these compatible with?

These caps are designed specifically for 5/8-inch smooth dowel bars.
