Seven pounds empty is what makes this base practical on a patio that gets packed away - drained, it carries to the shed in one hand. Filled with water it reaches 57 lbs, and a sand and water mix brings it to 90 lbs, which is the combination the maker recommends for the steadiest hold. Two adapters and an adjustable fitting take poles from 1.2 to 2 in. HDPE resists fading and cracking under sun, with a textured black finish that suits a modern patio. It measures 21.5 in across and 14.5 in tall. Assembly is required and a manual is supplied.
