TimberStrand® LSL treated sill plates are long and straight so walls get off to a square start. They install fast and crews don't have to waste time culling.

TimberStrand LSL Treated Sill Plates save time and hassle. Our patented StrandGuard® process treats these sill plates throughout the cross section so you don't have to worry about field treatment when you drill for anchor bolts. Our sill plates are also warranted against termites and fungal decay.
