Key Features
- Genuine OEM Material Consistency — Manufactured to the same density and compression characteristics as the original, maintaining the sealing and cushioning function the lower sponge is designed to perform.
- Drop-In Lower Position Fit — Shaped and sized to seat correctly in the lower sponge position, aligning with existing mounting points without trimming or reworking.
- Broad GBX-Series Coverage — Compatible with GBX24S, GBX24B, GBX12S, GBX12SK, and GBX24BK Towable Tower and Balloon System models.
- Maintains Structural Integrity of the Assembly — A worn or compressed lower sponge can allow unwanted movement or gaps within the unit; replacing it restores proper support and fit within the housing.
- Direct from Authorized Supply Chain — Sold by DHS Equipment as an authorized Multiquip parts distributor, so you receive a verified OEM part backed by the correct part number.
The lower sponge serves as a cushioning and sealing element positioned at the base of the assembly within GBX-series Towable Towers and Balloon Systems. It absorbs contact pressure, limits internal movement, and helps maintain alignment between components during operation and transport. When the sponge degrades, compresses permanently, or tears, it can no longer perform these functions effectively — leading to looseness in the assembly or accelerated wear on surrounding parts. Replacing it with the correct OEM part restores the fit and protection the assembly depends on.
