Complete perimeter seal and corner block replacement kit for toy hauler patios and car trailer ramp gates. Features a double-tab hollow half-round profile — tabs increase sealing surface contact when compressed and create a drainage channel to protect the trailer interior. High-quality EPDM sponge rubber, 11/16" H x 3/4" W. Kit includes 35 ft seal with 3M adhesive backing, ramp gate corner seal (trimmable), plastic scraper tool, Loctite Super Bonder 495, and detailed instruction sheet.
The Steele Rubber Products 90-3328-283 is a complete ramp gate seal replacement kit built around a large hollow half-round profile with double tabs — the key distinction from the standard half-round kit. The double tabs extend laterally from the top of the half-round dome on both sides. When the ramp gate closes and compresses the seal, the tabs flatten against the gate surface, dramatically increasing the total sealing contact area beyond what the dome alone provides. This wider compression footprint closes gaps more completely and maintains sealing contact even when the gate frame is not perfectly true or uniform.
The tabs also serve a secondary function: when compressed, they form a shallow channel along the base of the seal that guides moisture, road debris, and water away from the interior side of the gate seal — providing an additional line of defense against intrusion into the trailer. For toy haulers and car trailers that see heavy use, frequent ramp cycling, and significant road debris exposure, the tabbed profile offers a meaningful upgrade over a smooth half-round seal.
Like all Steele Rubber ramp gate kits, the 90-3328-283 is a complete installation package. The 35-foot strip seal has a 3M adhesive backing for securing the perimeter seal to the gate frame. The included trimmable corner seal handles the 90° transitions where strip seal alone cannot form a proper seal. Loctite Super Bonder 495 bonds the mitered corner joints into a seamless one-piece gasket. The plastic scraper removes old seal residue, and the detailed instruction sheet walks through the full installation process step by step.

35 ft seal with 3M adhesive, trimmable corner seal, plastic scraper, Loctite Super Bonder 495, and detailed instructions — every component for a full ramp gate seal replacement in one package
Will not shrink, crack, or fade — strong UV and ozone resistance for long-term outdoor performance through heavy daily ramp gate cycling and all-season weather exposure
Pre-formed ramp gate corner seal ships as a single piece and can be trimmed to fit your specific gate corner dimensions — seals the most vulnerable entry points on the full ramp gate perimeter
The ramp gate corner seal is included as a single trimmable piece — measure and trim to match your specific gate corner dimensions before bonding. For a seamless perimeter seal, the strip seal should be mitered at 45° at each corner transition where it meets the corner piece. Use the included Loctite Super Bonder 495 to bond all mitered joints into a seamless one-piece gasket. Use the included plastic scraper to completely remove all old seal material and adhesive residue from the ramp gate frame before applying anything new. Clean, residue-free bonding surfaces are critical for both the 3M adhesive strip and the Loctite corner bonds. Refer to the included detailed instruction sheet for complete step-by-step corner mitering and installation guidance.
Part Number: 90-3328-283 Choose the Tabbed Kit (This Item) When: • Your existing ramp gate seal has visible tabs or "ears" extending from both sides of the half-round dome • You want maximum sealing contact area for a ramp gate that sees heavy cycling or has a less-than-perfectly-true frame • Your application benefits from the drainage channel function the compressed tabs create Choose the Standard Half-Round Kit (90-3327-283) When: • Your existing ramp gate seal is a smooth large hollow half-round with no tabs Ramp Gate Seal Profile Options: Steele Rubber offers ramp gate kits in three profiles — Ribbed Hollow Bulb, Large Hollow Half-Round (no tabs), and Large Hollow Half-Round with Double Tabs (this kit). Always confirm which profile matches your existing seal before ordering. Note: The 35 ft strip seal and trimmable corner seal are sized for standard toy hauler and car trailer ramp gates.
Kit Includes (5 items): • (1) Large Hollow Half-Round With Double Tabs Seal — 11/16" H x 3/4" W x 35 ft, 3M adhesive backing • (1) Ramp Gate Corner Seal — 1" H x 3" W x 14" long (trimmable to fit) • (1) Plastic Scraper Tool — for removing old seal and adhesive residue • (1) Loctite Super Bonder 495 — for bonding mitered corner joints • (1) Detailed Instruction Sheet — step-by-step installation guidance NOT Included: • Isopropyl alcohol or adhesive remover for additional surface prep • Tape measure, miter cutting tools, or utility knife
Refer to the included instruction sheet for complete step-by-step guidance. 1. Remove Old Seal: Use the included plastic scraper to completely remove all old seal material and adhesive residue from the ramp gate frame — clean surfaces are critical for adhesion 2. Clean the Surface: Wipe the bonding surface with isopropyl alcohol and allow to fully dry before applying any new seal material 3. Trim Corner Seal: Measure your ramp gate corners and trim the included corner seal piece to fit — it ships as one piece designed to be cut to your corner dimensions 4. Miter the Seal: Cut the tabbed half-round strip seal at 45° at each corner transition point to create clean mitered joints 5. Bond Corners: Apply the included Loctite Super Bonder 495 to all mitered joints and bond the corner pieces — allow to fully cure before cycling the ramp gate 6. Apply Perimeter Seal: Peel the 3M backing a few inches at a time and press the tabbed seal firmly onto the gate frame along the full perimeter between corner pieces 7. Test Closure: Close and cycle the ramp gate to confirm the tabs flatten fully against the gate surface and the dome compresses evenly — a properly seated tabbed seal will show even compression across its full width
Steele Rubber offers three ramp gate seal kit profiles. Select the kit that matches the profile of your existing ramp gate seal.
All three kits include 35 ft of seal material, a trimmable corner piece, plastic scraper tool, Loctite Super Bonder 495, and a detailed instruction sheet. Always measure and confirm the profile of your existing ramp gate seal before ordering to ensure a correct replacement fit.
