Precision Universal 5mm Foam Underside Glass Molding w/ Tape | 100ft Roll | PRP05100USMF
✓ In stock — ships within 1 business day
Precision 5mm foam underside glass molding — EPDM sponge rubber that stays flexible in cold without shrinking in heat. The narrow 5mm profile suits vehicles with shallower glass channels. Pre-applied adhesive tape bonds directly to the glass edge. Sold per 100-foot roll for higher-volume shop use.
Specifications

Application
Universal fit — suited for vehicles with shallow glass channels. Verify channel measurement before ordering. Also available in a 75-foot roll (PRM05USMF) for lower-volume or single-vehicle use.
What does underside glass molding do?
Underside glass molding seats between the bottom edge of the glass and the vehicle's pinch weld or channel. It creates a consistent seal, cushions the glass against the body, and prevents direct metal-to-glass contact. Correct width selection is critical — too wide raises the glass; too narrow and it sits unevenly.
How do I know if 5mm is the right width?
Measure the depth of the glass channel or pinch weld. A 5mm profile is best for shallow channels found on many compact cars and imports. If the channel is significantly deeper, use a wider profile (7mm, 8mm, 9mm, or 10mm).
What is the difference between EPDM sponge and solid compound molding?
EPDM sponge compresses under pressure — ideal for tighter channels or vehicles with slight dimensional variation and easier to work around curves. Solid compound holds its shape without compression — best when the channel closely matches the molding width and a rigid, stable profile is preferred. Both bond to glass via pre-applied tape.
How much molding do I need per installation?
Most passenger vehicle windshields require 12–16 feet of underside molding. A 100-foot roll covers approximately 6–8 complete installations — the right stock quantity for shops doing steady windshield volume. The 75-foot roll (PRM05USMF) is available for lighter-use situations.
Is this compatible with both OEM and aftermarket glass?
Yes — cut to length on-site, this molding works with OEM and aftermarket replacement glass alike. Verify the channel dimension on the specific glass being installed, as aftermarket profiles can vary slightly from OEM.
