THIS DEAL OF THE DAY Ring Toss Knob (Single Hold Only) - WHITE IS 20% OFF! NO COLOR REQUESTS, NOT RETURNABLE.
This product has been designed so that you can build your own Ring Toss Obstacle. The knob measures 2-1/2", the shaft 1-1/2", and the base plate is 1" thick. There are six recessed attachment locations. The recesses are 5/8" OD so that when the ring loops over the knob, the ring will not graze the screw.
We don't currently sell hardware for this product as there are many types of material you can attach them to. For installation onto solid wood surfaces such as beams, we recommend the GRK 5/16" Structural Screws. We recommend at least a 2-1/2" embedment. If you are attaching to a solid wood beam, you should use a 3-1/2" to 4" long screw. See below for a photo example of the recommended screw for attaching to a solid wood beam.
For installation onto thinner surfaces such as metal, we recommend a through-bolt setup with 5/16" bolts, washers, and nuts. Below is one example of the hardware to use.
