Most baby safety gates include hardware to install the gate into a wooden stud, wooden doorway or other secure wooden base. In other situations, installation kits help create a proper mounting surface to securely install baby gates. Plus, installation kits can help prevent or minimize damage to walls and woodwork.
As you can see in the picture, our u-bolts are wrapped around 1 spindle from each crib side. When tightened, the tension will draw the 2 spindles together, pushing the sides outwards in the direction of the arrows safely securing the baby gate in place.
I work at a public school with students who have severe developmental disabilities. The only type of gate that we have found that meets our safety needs is the SAFETY 1st - The Curve Baby Gate. The gate works very well for us, because it is sturdy, and we serve students up to 5th grade, some of whom can physically open a single-step gate, but do not have the ability to operate The Curve's two-step process. The gate also cannot stop an older child who is tall enough and physically able to climb over the gate, however, it does tend to slow him down...The only other drawback is that it has been difficult to locate more of these gates.
