I love this gate! I got it to block my dogs off from eating the cat food! I love the pet door, it's spring loaded and I did not screw the end caps into my my opening! I didn't need to! With the cat door, they don't jump over the gate and the dogs haven't attempted to push threw it! If they decide to push the envelope, then I will screw them in, but it's sturdy enough without them! I love this!!! It has helped tremendously! And an added bonus,,,you can't beat the price!
