Simpson Strong-Tie
$12-$35 eachStandoff Post Bases for Maximum Air Circulation and Rot Prevention
Standoff post bases elevate wood posts significantly above concrete, maximizing air circulation and preventing moisture contact that causes rot. With standoff heights from 1 to 6 inches, they keep vulnerable end grain above standing water, splash zones, and snow.
Key Features
- Maximum elevation above concrete
- Superior air circulation at base
- Prevents moisture wicking into end grain
- Hot-dipped galvanized construction
- Fits 4x4 and 6x6 posts

Frequently Asked Questions
1-2in in most climates. 3-6in in wet climates, near sprinklers, or where snow accumulates. Higher standoffs provide better ventilation but may need bracing.
No. Quality standoff bases have published load values meeting structural requirements when properly installed.
