The PGA Tour umbrella holder can be easily fixed onto your golf trolley thanks to the wing nut and bolts that need no additional tools. The holder has a special rubber insert to prevent it from slipping and there is a lever to hold it firmly in place. It is also adjustable to any desired angle to provide great rain protection. The holder is suitable for most push, pull and electric trolleys and can be adjusted to any round or square tubing 15mm to 30mm (0.6” to 1.2”).
