The Malco FSXS Power-Assisted Standing Seam Seamer locks 1″ and 1.5″ mechanical lock panels quickly and consistently using your cordless drill. Designed to seam both single-stage (90°) and double-stage (180°) locks in one efficient pass, this tool eliminates the need for hand seamers and dramatically reduces installation time.

With speeds up to 98 feet per minute, the FSXS allows crews to seam large roof sections with precision and uniform pressure from start to finish. It is engineered to begin seaming at the start of the panel profile without pre-closing by hand, improving workflow and reducing fatigue on the jobsite.

Built for professional metal roofing installers, the FSXS handles steel, stainless steel, aluminum, copper, and zinc panels. The adjustable pressure system allows fine-tuning based on material thickness and panel profile to ensure clean, tight seams without deformation.

Each unit ships in a rugged IP67-rated waterproof hard case with custom foam inserts to protect your investment between jobs.

If you’re installing 1″ or 1.5″ mechanical lock panels regularly, this is the fastest and most consistent way to close seams in the field.
