What happens here

Before installing the J-trim, you need to accurately measure the length of your first run. The presenter advises measuring to the middle of a floor joist or truss if possible. This ensures that the J-trim can be securely fastened at the joint and prevents two pieces from joining in an unsupported section.

Goal: Determine the correct length for the initial piece of J-trim.

Tools and materials

  • Pencil — Marking measurements on the J-trim
  • Tape Measure — Measuring the length of the J-trim sections

What they say

Hide

Before I put metal on the ceiling, I need to J-trim the whole perimeter. Let's get after it. First things first, you're going to want to measure your first run. Make sure when you measure, you measure to the middle of your floor joist, your truss. You don't want to have two pieces joining right here. You want to be able to fasten it. Now, to fasten this J-trim up here, I'm using 18-gauge crown staples. Make sure you set the depth of your nailer, so you don't blow through the steel.
