Use this RV vinyl trim molding insert and screw-cover selection guide to compare the flexible strips that conceal exposed fasteners inside compatible aluminum molding channels. This is about the removable vinyl insert—not the aluminum corner, roof-edge or gutter extrusion beneath it.
Manufacturer reference and genuine profile illustrations
AP Products distinguishes 3/4-inch flexible screw cover, 7/8-inch flexible screw cover, 3/4-inch insert molding trim, and 1-inch vinyl trim insert. These are different product families even where their widths are close. Compare the original profile in AP Products' screw-cover and insert catalog or the illustrated historical AP Products reference (trim insert section).
Compare the screw-cover profile with your existing aluminum channel, then select the correct width, finish and roll length.
Start with the channel and original insert width
011-398 polar white, 011-399 black, and 011-444 bulk polar white. Confirm the original lip/retention profile before changing brand or series.
011-407 polar white. The related black 011-408 family needs an exact package-number match before being linked here.
011-331 colonial white, 011-306 white, and bulk 011-311 white / 011-312 black. Measure the original strip at an undamaged section.
Compare the molding groove width, lip shape and retention tabs. Nominal insert width by itself does not establish a fit in any specific aluminum rail.

View partColour and roll length matter
White, polar white and colonial white are separately named manufacturer finishes, not guaranteed identical shades. The AP Products part number controls the selected colour and roll length. Bulk lengths such as 200 or 1000 feet should be considered separately from shorter retail rolls; confirm package contents and shipping terms on the exact listing.
Choosing a black 7/8-inch insert
AP Products lists 011-408 as a black 7/8-inch flexible screw cover in a 50-foot roll. The separately numbered 011-408-25 is a black 7/8-inch insert in a 25-foot roll. The two packages are different lengths. Compare the original molding channel and order by the complete part number rather than an abbreviated stock number. View the 011-408-25 black 25-foot insert.
Replace the insert, not the roof sealant
The vinyl strip typically covers fasteners and finishes the aluminum molding. It should not be treated as a replacement for the sealing material below the metal molding. If roof-edge trim is loose, screws have corroded, or there are signs of leaks, inspect and repair the underlying joint according to the RV roof-system manufacturer's instructions before installing new vinyl. Do not block drainage paths.
See the separate aluminum roof-edge, corner and gutter trim guide for the rigid extrusion beneath the insert. Browse the molding and insert collection to compare additional sizes and finishes.
