The Multiquip A300394500 Upper Sponge is a genuine OEM component designed for GBX-series towable towers and balloon systems, including GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK models. Sourced directly from Multiquip, this part matches the original specification for a straight-forward, no-guesswork replacement. Keeping the correct sponge in place ensures the balloon lighting system maintains its intended light diffusion and sealing performance in the field.
Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's original sponge density and compression spec, ensuring consistent contact and sealing performance at the upper balloon interface.
- Direct Drop-In Replacement — Designed to seat exactly as the original, with no trimming or fitting required during installation on compatible GBX units.
- Broad GBX Series Compatibility — Fits GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK towable towers and balloon lighting systems.
- Protects Balloon Integrity — A properly functioning upper sponge cushions and supports the balloon envelope at its upper mounting point, helping prevent abrasion, tearing, or premature wear of the balloon material.
- Verified Multiquip Part Number — Ordering by part number A300394500 confirms you receive the correct OEM component for your specific GBX equipment, eliminating costly ordering errors.
The upper sponge sits at the top mounting point of the balloon lighting assembly, acting as a cushioning and sealing interface between the balloon envelope and the rigid tower structure. It absorbs vibration and movement during operation and transport, protecting the balloon from chafing or stress tears at the contact point. When this sponge compresses, degrades, or tears, the balloon becomes vulnerable to accelerated wear at that junction, which can shorten the service life of the entire balloon assembly.
