Heavy-Duty Southern Yellow Pine Construction

Precision Fit for DR21 HDPE Mortar Tubes

A machined beveled edge helps simplify installation and promotes a secure, uniform fit inside compatible DR21 HDPE mortar tubes. The natural compression characteristics of solid wood allow the plug to grip the interior of the tube securely, creating a strong and dependable base.
