XEEP Aluminum RV Bumper End Caps 2-Pack for 4" Square Bumpers — Weatherproof, Vented Storage

XEEP Aluminum RV Bumper End Caps are a two-piece, robust replacement set designed to securely seal 4" square camper bumpers while storing sewer hoses and other gear.

If your travel trailer, motorhome or camper has lost factory bumper plugs or you want a more durable option than plastic, these aluminum bumper end caps offer a weatherproof, ventilated solution. Built to resist rust and vibration, the set includes two caps plus a simple, tool-light installation kit so you can replace or upgrade bumper ends in minutes.

How do these bumper caps stay firmly attached on the road?

The XEEP caps use a precision locking buckle and keyed anti-loosening fasteners to prevent movement, rattling, or loss during travel. The design secures tightly to a standard 4" square bumper and includes spare cable ties for added reinforcement.

• Precision locking buckle for stable engagement
• Anti-loosening screws to resist vibration
• Three extra disposable cable ties for secondary security

What materials and protections do these caps provide?

Made from high-grade aluminum, the bumper end caps resist corrosion and stand up to weather exposure better than common plastic alternatives. Their metal construction provides long-term protection for hose storage and bumper ends while remaining lightweight.

• Rust-resistant aluminum construction
• Weatherproof finish suitable for outdoor use
• Durable against knocks, UV exposure, and road debris

Will the caps keep stored hoses dry and odor-free?

Yes — the caps feature small, densely arranged vent holes that encourage airflow while keeping out leaves and grit. This ventilation helps reduce trapped moisture and limits unpleasant smells inside the storage cavity.

• Multiple vent holes for circulation
• Designed to block debris while allowing airflow
• Helps prevent mildew and lingering odors

How easy is installation and what’s included in the kit?

Installation is largely tool-free and designed for quick fitment on standard 4" square bumpers. The kit arrives with rubber buffer pads and the small tools needed to tighten the locking hardware so you can finish the swap without a full toolbox.

• Includes 2 aluminum bumper end caps and 4 rubber buffer pads
• Comes with a spanner and hex wrench for final tightening
• Includes 3 cable ties, 5 informational cards, and clear instructions

Who is this for: These XEEP aluminum bumper end caps suit RV owners, travel trailer and motorhome users who need a long-lasting replacement for lost or broken bumper plugs, or anyone wanting a sturdier upgrade from plastic caps. They’re especially useful for frequent travelers, storage-minded campers, and those who carry sewer hoses or bulky items on bumper-mounted tubes and need a secure, ventilated closure.
