Superior grade 100% EPDM sponge rubber rectangular extrusion with softly rounded top edges and bonded 3M Peel-N-Stick adhesive. Rounded edge profile delivers a smooth, finished appearance on exposed sealing surfaces — suitable for any edge that needs sealing. Ideal for replacing worn compartment door, hatch, and window seals. Hand crafted and made in USA.
The Steele Rubber Products 83-1029-277 is a 7/16" high by 11/16" wide EPDM sponge rubber rectangular extrusion with softly rounded top edges and a bonded 3M Peel-N-Stick self-adhesive strip. While it shares the same 7/16" H x 11/16" W footprint as the square-edge rectangular extrusion (83-1033-277), the rounded top edge profile is the key distinction: where the square-edge version seats in channels and delivers a crisp mechanical fit, the rounded edge profile is engineered for surface-mount applications where the top of the seal is visible and a smooth, finished appearance matters. The gentle radius on the top edges eliminates the sharp corners that can catch debris or create pressure points on door faces and panel surfaces.
Constructed from 100% EPDM sponge rubber, this extrusion resists moisture, ozone, and UV exposure and will not fade, shrink, or crack. The flat adhesive base adheres securely to clean, dry RV door frame and panel surfaces, while the rounded top compresses evenly against the mating surface when the door or hatch is closed. This versatile seal can be used on any edge or surface that requires sealing, cushioning, or a finished appearance. Available in 10 ft and 30 ft pre-cut lengths and by the foot, and backed by Steele Rubber Products’ 100% Satisfaction Guarantee.

The rounded edge profile is particularly well-suited for applications where the seal top surface is visible or where a smooth finished compression surface is preferred over a sharp square edge: Exterior Compartment Door Frames: Surface-mount replacement for worn rectangular-profile seals on storage bay and utility compartment door frames where a clean, rounded profile is desired Roof Hatches and Skylights: Rounded top edges compress evenly against hatch covers and provide a polished finished look around roof openings Access Panels and Entry Doors: Suitable for access panels and entry door frames where a visible seal edge is part of the finished door appearance Window Frame Perimeters: Rounded profile seals window frame edges without the hard corners that can mark window frame finishes or catch during opening and closing Panel Edge Sealing: The rounded profile is designed for use anywhere there is an exposed edge that needs sealing — interior panel edges, trim channels, and utility openings throughout the coach Cushioning and Vibration Dampening: Rounded top profile provides smooth cushioning between panels or components where a soft contact surface is preferred No specific RV model fitment list is available for this part. The rounded rectangular profile is a general-application seal. Always verify that the 7/16" H x 11/16" W profile and surface type match your specific application before ordering.
The bonding surface must be completely clean and dry before applying the seal. • Remove all old seals, adhesive residue, and debris using a general-purpose adhesive cleaner or rubbing alcohol • Allow the surface to dry completely — applying over wet cleaner prevents adhesion • Apply within the recommended temperature range: 60–104°F (15–40°C) • Minimize the temperature difference between the seal and the bonding surface • The 3M adhesive bonds immediately on contact — work a few inches at a time and do not remove all backing at once Unlike the square-edge rectangular profiles, the rounded edge extrusion is primarily designed for surface-mount applications rather than channel installation. Ensure the mounting surface is smooth and flat for maximum adhesive contact along the full length of the seal base.
Step-by-Step Installation: 1. Remove Old Seal: Pull the existing weatherstrip from the door frame or panel surface, working around the full perimeter 2. Clean the Surface: Remove all old adhesive, residue, and debris using adhesive cleaner or rubbing alcohol 3. Dry Completely: Allow the bonding surface to dry fully before applying the new seal 4. Check Temperature: Confirm both seal and bonding surface are between 60–104°F (15–40°C) 5. Cut to Length: Measure and cut strip sections using a sharp utility knife or scissors 6. Peel & Apply: Remove the backing a few inches at a time — do not remove all backing at once 7. Press Firmly: Apply steady, even pressure along the full length, ensuring the flat adhesive base makes full contact with the mounting surface 8. Corner Joints: Apply a small amount of cyanoacrylate adhesive (super glue for rubber) at end-to-end corner joints for full perimeter seals 9. Allow to Cure: 3M adhesive bonds immediately on contact; allow adequate time to fully set before heavy weather exposure
In The Package: • One (1) continuous 10 ft strip of 83-1029-277 Peel-N-Stick Rectangular Rounded Edge Sponge EPDM Extrusion Seal • 3M adhesive backing pre-applied and protected by release liner Recommended Supplies (Not Included): • Adhesive cleaner or isopropyl rubbing alcohol for surface preparation • Disposable rags or shop towels • Sharp utility knife or scissors for cutting seal to length • Cyanoacrylate adhesive (super glue for rubber) for corner and end-to-end bonding on full perimeter installations • Steele Rubber 83-1033-277 Square Edge Rectangular Extrusion (sold separately) if a channel-mount square-edge profile is required instead
Both the rounded and square edge rectangular extrusions share the same 7/16" H x 11/16" W footprint. The choice between them comes down to the application type and whether the seal top surface is visible: 83-1029-277 — Rounded Edge (This Item): Best for surface-mount applications where the top of the seal is visible or where a smooth, soft contact surface is needed against the door face or panel. The rounded profile avoids hard corners that can trap dirt, mark surfaces, or create uneven compression. 83-1033-277 — Square Edge: Best for channel-mount applications where the seal is recessed into a rectangular groove in the door frame, or where a crisp square edge is needed to fill the channel opening cleanly. The flat sides seat mechanically in the channel for dual retention. Tip: If the existing seal has visibly rounded top edges, replace with the rounded profile (this item). If the existing seal has sharp, flat sides and seats in a channel groove, use the square edge profile (83-1033-277).
The rounded edge profile is the finishing touch on RV sealing applications where appearance and smooth compression contact matter as much as weatherproofing. By radiusing the top edges, this extrusion delivers both function and a clean finished look on any exposed sealing surface across compartment doors, hatches, windows, and panel edges.
