Upper Replacement extension cap for Safety 1st Baby Gate. Originally designed for model Item Number: GA107-S1-US-EN. With multiple rescue dogs we needed to add an additional gate but seemed to be missing the upper extension cap. I found several variations online but none for the model gate we had. After a few trial and errors I got this designed and printed up. It's a tight fit but so far it has held the gate with 6 rescue dogs behind it!
