Treasure Garden Replacement Base Knob (Set of 2, Black Finish) Frequently Asked Questions
What exactly does this base knob set replace or fit?
This replacement knob set is designed specifically for Treasure Garden umbrella bases including the BA150, BA50, BG50, BKM, BW50, BS35 and BS70 series. It provides the black-finished thumbscrew that secures the umbrella pole in the base stem.
What is included in this set and what are the specifications?
The package includes two (2) black knobs with thread size M8 × 49.7 mm. Perfect for replacing worn, damaged, or missing knobs on compatible Treasure Garden umbrella bases.
How difficult is it to install the replacement knobs and do I need tools?
Installation is straightforward: remove the existing knob on your umbrella base stem, thread the new M8-49.7mm knob into the same location and tighten securely by hand. No special tools are required beyond loosening the old knob and tightening the new one. Make sure the umbrella pole is properly seated and the knob clamps it securely.
Why would I need to replace the base knob and how often should I check it?
Over time the knob can become stripped, corroded, damaged by weather exposure, or simply lose its grip—especially in frequent use outdoor setups. Replacing it when you notice slippage of the umbrella pole, difficulty tightening, or visible wear helps maintain safe and stable umbrella installation. Regular checks (seasonally or before heavy use) are recommended.
Will the black finish match the rest of my umbrella base and is it weather-resistant?
Yes — the finish is matched for Treasure Garden’s outdoor base hardware, so the black knob integrates visually with the base. Although it's a replacement part, it’s designed for outdoor use and built to withstand standard patio conditions. That said, it’s still wise to wipe off debris and corrosion occasionally for best performance.
What if I have a different model or size umbrella base—will these knobs still work?
These knobs will work only for the series listed (BA150, BA50, BG50, BKM, BW50, BS35, BS70). If you have a different model or if your stem uses a different thread size than M8 × 49.7 mm, this set will not fit properly. Always verify your base model and knob thread specification before purchasing.
