Porter Manual Center-Strut Height Adjuster; Double Drop For Rect Board

The Manual Center Strut Height Adjuster in Double Drop configuration is the practical, low-maintenance solution for large gymnasiums with high structural ceilings that need extended drop length to reach regulation playing height. It gives facility managers a dependable, electrically independent adjustment system that works every time without motors, wiring, or control electronics to troubleshoot.

• Double Drop Extended Frame – Provides the additional vertical drop length needed in high-ceiling gymnasiums to bring a ceiling-suspended backstop from the structural ceiling down to the regulation 8'–10' basketball goal height range, covering installations where a standard single-drop unit cannot reach playing height
• Manual Crank Operation – Entirely mechanical height adjustment with no electrical components, motors, or wiring requirements — the simplest and most maintenance-free configuration in Porter's center strut lineup, ideal for facilities that prefer straightforward operation and minimal system complexity
• Portable Operator Kit Compatible – Supports use of Porter's No. 00900-259 Portable Operator Kit, allowing facility staff to perform height adjustments from a more accessible position without a standard power drill, improving safety and ease of operation during routine height changes
• Full 8'0" to 10'0" Height Range – Adjusts across the complete regulation basketball goal height spectrum in a single unit, converting the gym between youth, junior high, and varsity competition heights between sessions without additional hardware or equipment changes
• Center Strut Structural Stability – Centered attachment design distributes the backboard load symmetrically throughout all height positions, preventing lateral instability or board lean during adjustment and ensuring consistent alignment during play at every height setting
• Porter 500 and 600 Series Compatible – Engineered to integrate directly with Porter's 500 Line and 600 Series ceiling-suspended and wall-mounted backstop systems, maintaining full mechanical compatibility and manufacturer warranty coverage for the complete installation
