Wooster Brush R138-3 Zip Trim Roller and Tray 3 in

Product Description

The WOOSTER BRUSH R138-3 is a compact trim roller kit designed for precise paint application on narrow surfaces such as door casings, window trim, baseboards, and cabinet edges. The kit includes a 3-inch trim roller frame with a 3/16-inch nap roller cover and a dual-purpose packaging tray that converts into a ready-to-use paint tray. The low-profile roller frame allows the applicator to work close to corners and adjacent surfaces without over-brushing. This kit is sold in a package quantity of four, making it practical for job-site restocking or crew distribution.

The R138-3 is suited for residential and light commercial interior painting work where trim and detail surfaces require a smaller roller rather than a standard 9-inch frame. It is commonly used by finish painters, general contractors, and skilled DIYers working on trim-out phases of construction or renovation projects. The 3-inch roller width keeps paint control tight along edges, reducing masking time and cleanup labor on adjacent drywall and flooring surfaces.

Compatibility

Designed as a compact trim roller kit compatible with standard water-based and oil-based paints suitable for 3/16-inch nap roller covers on smooth to lightly textured trim surfaces.

Installation Notes

No mechanical installation is required. Load the roller cover by rolling it in the converted package tray with a moderate amount of paint, distributing evenly before application. Ensure the roller cover is fully seated on the frame before use to prevent slippage. Follow paint manufacturer guidelines for surface prep, dry times, and cleanup solvent selection.
