The Rubberseal Upstand Trim Joint Clip is a purpose-designed connector for joining adjacent upstand trims within EPDM and similar flat roofing systems.

When multiple lengths of upstand trim are installed along a roof edge, precision alignment is critical. Even minor movement at the joint can affect both appearance and long-term performance.

This joint clip bridges the gap between adjoining trims to:

Maintain a straight, consistent trim line

Reduce stress concentration at connection points

Improve overall structural stability

Deliver a sharp, professional perimeter finish

It also holds adjoining trims firmly in position during installation, making alignment quicker and more accurate.

Whether used on domestic extensions, garages or commercial flat roofs, the Upstand Trim Joint Clip enhances both durability and aesthetics.

It’s a small component — but a key detail in delivering a properly finished EPDM roof edge.
