Top Line Manufacturing RBIS12030 RV Bunk Ladder Interior Step

The Top Line Manufacturing RBIS12030 is an interior bunk ladder step engineered for RV bunk bed applications. Designed as an OEM-grade component, this step delivers the same reliable construction that has made Top Line a trusted supplier to major RV manufacturers for over 45 years.

Key Features:

• High-strength aluminum construction — built from 6063-T6 aluminum alloy for a durable, lightweight design
• Anodized satin finish — corrosion-resistant finish on rails and step surface for lasting appearance
• Padded step surface — non-slip padding provides a warm, cushioned feel underfoot, even barefoot
• No exposed fasteners — clean, finished appearance with all hardware concealed for a professional, factory-installed look
• Smooth, snag-free edges — all parts finished to eliminate sharp edges that could catch clothing or cause injury
• No-slip, no-mar bumper pads — floor-contact bumper pads protect RV interior surfaces and prevent movement

The RBIS12030 is a purpose-built interior bunk ladder step suitable for use as a replacement or upgrade in motorhomes, travel trailers, fifth wheels, and toy haulers. Top Line's interior bunk steps are used by leading OEM manufacturers and are designed to mount securely to standard bunk rail configurations for safe, reliable access to upper sleeping areas.
