How to Install a Mammoth Basketball Hoop

By Peter Forsythe

Of the several lines of consumer basketball hoops manufactured by Lifetime Products, its Mammoth series is as close as you can come to the experience of playing on a professional goal. With dunk-withstanding spring-flex rims, real glass backboards encased in black steel and a single-pole anchoring system that minimizes wobble and vibration while allowing for precision leveling, Mammoth goals are built to withstand ferocious gameplay. Installing one of these hoops begins with careful location planning, as well as the necessary mixing and leveling for a solid foundation.

Step 1

Pick the exact spot where the hoop will go and dig 48 inches deep square hole measuring 21 inches across. The near edge of the hole should line up to he basketball playing surface, be it a street, driveway or court.

Step 2

Screw a 5/8-inch hex nut all the way down on each j-bolt, then insert the threaded ends through the corresponding holes in the j-bolt template. Once you secure these bolts with 5/8-inch hex nuts, insert the bolts down through the center hole in the j-bolt template and tighten the nut coupler securely onto the bolt.

Step 3

Mix the concrete in accordance with the instructions on the bag, then pour the wet concrete into your hole, leaving about 18 inches of space to the top. Then push the four 36-inch rebars firmly into the bottom of the hole, arranging them in a square 8 inches wide. This way, each rebar piece will be next to the j-bolt when it's inserted into the cement.

Step 4

Fill the rest of the hole with concrete, topping it off about 1/2-inch above the playing surface. Then center the j-bolt template over the hole, with the front end toward the playing surface. Insert the protruding ends of the j-bolts into the concrete and push down until the template sits flat.

Step 5

Use a carpenter's level to make sure the template is level with the playing surface, and clean off any concrete left on the template, or the above-ground ends of the j-bolts. After three days, the concrete will cure and the base installation will be complete. All that remains is the assembly of the pole and hoop itself, for which you can refer to the instruction manual for model-specific instructions.
