When it comes to fixing door hinges, having the right tools makes everything easier. That’s why professionals often rely on these three go-to stainless steel solutions from Waterson—for both installation and adjustment. But what are they? Let’s find out.

1)Metal Door Shims

A metal door shim is a thin, flat material placed between the hinge and the door or frame to correct alignment issues. It ensures smooth operation, helps to adjust uneven door openings, and prevents binding.

Waterson metal door shims are made of 304 stainless steel with 3 hours UL fire rated and double-sided tape. For commercial, residential, and industrial doors, this is a recommended solution for hinges adjustment.

2) Stainless Steel Door Stopper

Door stoppers prevent doors from swinging too far risking damaging walls, furniture, and/or the door itself. Different from traditional wall or floor-mounted door stops, Waterson stainless steel door stopper has a seamless design of a collar that fits snugly over the hinge barrel. The design helps to provide safety, preventing children to fall because of the wall-mounted door stops.

3) Hinge Helper

A hinge helper is an installation and alignment tool of door hinges. Waterson stainless steel hinge helper is a 3-functions-in-1; bending, propping, and holding the door. Use it when:

  • Installing new doors (holds hinges in place while drilling).
  • Fixing misaligned doors that stick or won’t latch.
  • Replacing hinges without door sagging.

Waterson stainless steel hinge helper resolves sagging, sticking, and misalignment.

For hinge repairs or installs, these three stainless steel tools—metal door shims, door stopper, and hinge helper—offer practical, durable solutions. They’re built for real-world use, saving time and reducing on-site hassle. Backed by Waterson’s manufacturing and engineering, these tools deliver smooth, long-lasting, and reliable door installation and adjustment every time.

Unlike plastic or coated metals, stainless steel offers corrosion resistance, strength, and longevity. Ideal for high-traffic areas, exterior doors, and humid environments.

Waterson door stopper finishes are available in Satin Brushed, Flat Black, Dark Bronze, and Stain Brass.

To fix a gap on the hinge side of a metal door, use a metal shim behind the hinge to adjust the door’s position and close the gap.
