Tiny whoop racing gate base(s).
Made for these agility hoops: https://amzn.to/2Xvublc
and this EL wire kit: https://amzn.to/2K5pFH0
Hook and Loop straps: https://amzn.to/2F2r110
Command Strips: https://amzn.to/2F0Y99D
The extended base uses an 1/2" dowel rod cut to the desired height. The agility ring just pops into the mount and is held pretty securely by the design. Can be used with or without the EL Wire.
Command strips or hook and loop straps work well to secure the bases on a vertical surface.
