How to Cut Edge Trims: Techniques, Tools, and Tips

Edge trim is fast and simple to install. All you'll need is your trim, cutting tools, and a little bit of DIY know-how.

Whether your edge trim is being applied to a sheet of material, a vehicle's door or window, furniture, machinery, or a marine vessel, you must measure and cut the trim carefully to avoid wastage and enhance its effectiveness.

We've put together a quick guide to cutting edge trim to help you successfully measure and cut your rubber trim ready for installation.

Different types of edge trim

Before you can get down to business, you'll need to check that you've got the right type of edge trim for your project.

Several different types of edge trim are available, each with unique qualities. Here at Seals Direct, the main types of edge trim that we sell are:

  • Standard PVC edge trims – Your average PVC edge trim is applied to panels, windows, and doors to protect the surface and those that come into contact with it.
  • Edge trims with seals - These trims create seals on doors, windows, hatches, lockers, and cabinets to prevent the ingress of water, air, and debris.
  • Plastic-reinforced edge trims – The plastic rather than metal spine on these trims makes them non-conductive and non-rusting.
  • FDA-approved silicone edge trims – These trims are safe for use in environments where food and drugs are processed and stored.

Materials and tools for cutting edge trim

Edge trim is usually sold by the metre, so you'll need to measure the material it is being applied to and then cut your trim to size before fitting it. So, how to cut edge trim?

Because most edge trim features a metal self-gripping spine, you will need to use a cutting tool that can handle metal. We recommend a straight-edge clipper or tin snips. It's important to take care not to put pressure on the trim when cutting, or it can crush or deform the trim's shape.

Techniques for cutting edge trim

You may sometimes need to create a mitred corner with your edge trim. To achieve a perfect mitred corner, we recommend using a 90-degree mitre tool rather than tin snips. Mitred corners usually require angled cuts in the face of the edge trim made at a 45-degree angle.
