Dual-Purpose Joining Clip & 90° Corner Detail

These universal metal edge trim connectors are designed to join and form corners with our universal metal edge trims used on EPDM rubber roofing systems. They provide a simple, professional way to connect trim lengths or create clean 90° external corners without bending the metal trim itself.

Available in 75mm, 100mm and 150mm sizes to match corresponding universal metal edge trims.

What They’re Used For ▸
  • Joining two lengths of universal metal edge trim
  • Forming a 90° external corner detail
  • Maintaining alignment across roof perimeters
  • Creating consistent, professional trim detailing

Not a waterproofing component – the EPDM membrane provides the waterproof layer. These connectors align and support the metal trim sections.

Why They Matter ▸

Trying to bend edge trims for corners can lead to distortion, cracking of the coating, or uneven lines. Using a dedicated connector:

  • Keeps perimeter runs straight
  • Creates a clean 90° trim junction
  • Reduces stress on the trim coating
  • Improves overall finish quality

It’s a small component that makes a visible difference on completion.

Installation Overview ▸

As a Joining Clip:

  • Slot the connector behind the first trim section approximately halfway.
  • Leave the exposed receptor edge ready to accept the next trim length.
  • Slide the adjoining trim into position and fix as normal.

As a 90° Corner:

  • Rotate the connector 90 degrees.
  • Slot it behind the trim at the corner edge.
  • The formed receptor edge allows the adjoining trim to slot in at a clean right angle.

A Roofer’s Perspective ▸

They save time on site. Instead of trying to crease or bend trims neatly, you get a consistent corner every time. On longer runs, they keep everything aligned and looking sharp.
