Cobra™ Rods by Sashco®

Targeted Wood Preservative for Log Homes and Timbers

Cobra™ Rods by Sashco® are an effective, long-lasting solution for protecting logs and timbers from rot and decay. Designed to treat the areas most prone to moisture damage — such as log ends, ground-contact posts, and splash zones — Cobra™ Rods deliver concentrated preservative where it’s needed most. By inserting these borate and copper rods directly into the wood, you can stop active decay and prevent future damage, even on logs already coated with a finish.

Ideal for log homeowners, contractors, and anyone maintaining exterior wood structures, Cobra™ Rods help preserve the structural integrity and beauty of your wood for years to come.

Why Choose Cobra™ Rods?

✅ Prevents and Stops Rot
Cobra™ Rods are designed for decay-prone areas like log ends, water-exposed posts, and damp timbers. They not only prevent rot but also arrest active decay in its early stages.

✅ Dual-Biocide Formula
Each rod contains copper and borate — two proven, EPA-approved wood preservatives. As moisture activates the rod, these ingredients gradually diffuse into surrounding wood fibers for lasting protection.

✅ Safe and Environmentally Friendly
Made with safe, effective preservatives, Cobra™ Rods protect your wood without harming the environment.

✅ Easy Installation and Maintenance
Simply drill the recommended holes, insert the rods, and seal. If a rod dissolves over time, it can be easily replaced to maintain protection.

How Cobra™ Rods Work

When installed into damp or wet wood, Cobra™ Rods dissolve slowly and release borate and copper deep into the wood fibers. This creates a protective barrier that prevents decay fungi from growing and spreading — protecting your logs from the inside out.

Cobra™ Rods can prevent rot for up to 8–10 years when properly installed and maintained.
