  • Description

    The Malco FSHS Standing Seam Hand Seamer is designed to close both the first-stage (90°) and second-stage (180°) locks on 1″ and 1.5″ mechanical lock standing seam systems.

    This tool works on vertical leg seams with 1/2″ width and provides consistent seam closure while protecting painted panel finishes. Replaceable PVC inserts prevent surface damage, and rubber grommets help maintain grip during operation.

    Ideal for field corrections and detail areas, the FSHS also pairs with Malco’s power-assisted seamer for efficient mechanical lock installation.

Malco FSHS Standing Seam Hand Seamer – 1″ & 1.5″ Mechanical Lock

Frequently Asked Questions

What stage of mechanical lock seam does this tool close?

Both FSHS and FSHS2 are designed to close first-stage (90°) and second-stage (180°) mechanical lock seams by hand. This allows contractors to fully close mechanical lock standing seam panels without needing a power seamer.

Will this hand seamer scratch painted metal panels?

No. Both FSHS and FSHS2 models feature replaceable PVC jaw inserts that protect painted or coated panels from scratching during seam closure. Rubber grommets also help prevent slipping while applying pressure.

Can this tool be used instead of a power seamer?

Yes. These seamers can fully close mechanical lock seams manually. However, many contractors use them in combination with a power seamer for increased speed on large roof areas, while using the hand seamer for:

  • Eaves
  • Ridge transitions
  • Tight spaces
  • Repairs

Is there a special technique for clean seam closure?

For best results:

  • Ensure the first-stage bend is straight and properly formed.
  • Apply even pressure along the seam.
  • Work progressively down the seam rather than forcing the entire length at once.

This prevents rippling and ensures tight, uniform closure.

What seam heights does the FSHS work on?

The FSHS is designed for 1″ and 1.5″ mechanical lock panels with a 1/2″ seam width.

If you are working with 2″ mechanical lock seams, use the FSHS2 model instead.

What is the maximum material thickness for the FSHS?

The FSHS is rated for:

  • Steel: up to 24 gauge
  • Stainless steel: up to 26 gauge
  • Aluminum: up to .040″
  • Copper: up to 20 oz
  • Zinc: up to 1 mm

Always stay within these limits to maintain proper seam closure and tool longevity.
