What This Product Does

The upper Tenax component forms part of the cover's attachment system, connecting with the corresponding lower fitting. Its role is cover retention, not fabric repair or roof sealing. OE Match supplies replacement components developed around Porsche applications.

Functions

• Provides the upper component of the Tenax fastening connection.
• Retains the cover at the corresponding attachment point.
• Replaces a missing or damaged upper fitting during cover refurbishment.

Diagram quantities describe the relevant assemblies, not the number of fasteners supplied with this product. Lower Tenax fittings, cover fabric and other diagram components are distinct parts.

Symptoms of Fault

A missing or broken cover fastener warrants inspection. Split stitching, cracked fabric or a cover that has shrunk can also affect attachment, so check the surrounding material before attributing poor fit solely to the upper fitting.

Why Replacement Matters

Renewing a damaged upper fitting addresses an incomplete fastening connection. Inspect its lower counterpart and the cover's mounting area at the same time; replacing this component will not correct torn material or a mismatched attachment.
