I bought this pool skimmer from Amazon for my pool. This particular model is designed for use with Intex pools that have a through-the-wall, screw type pump port. Coleman pools, unfortunately, do not. This adapter is inserted into the hose port on the pool and the clamp on the outside (over the hose) keeps it in place. The skimmer hose then just slides up over this. There is a ridge in the skimmer hose that mates with the ring around the coupler to keep it in place - no clamp is necessary.
NOTE Due to either a Thingiverse bug or (more likely) shadowbanning, my models no longer show up under the [Newest] listings. If you want to see more of my models, please be sure to 'follow' me.
