Frequently Asked Questions
Why does a frameless door need both a top and a bottom pivot hinge?
A frameless glass door has no frame to carry it, so it pivots on two points — one at the top, one at the bottom. The bottom pivot carries most of the door weight, and the top pivot keeps the door vertical and controls the swing. Using both together is what lets a heavy glass door open smoothly without sagging.
How is the door weight distributed between the top and bottom pivots?
In a standard frameless pivot set the bottom pivot takes the majority of the door load, which is why the bottom fitting is the heavier-duty piece, while the top pivot mainly guides the swing and holds the door upright. The design keeps the glass edge off the floor, so the door does not drag on tiles as it opens.
What glass thickness is this top-and-bottom pivot hinge built for?
The pivot set is designed for frameless doors in the 8–12mm tempered glass range, with the glass drilled or clamped at the pivot points. The bottom pivot and top pivot are matched to the same door, so the set works as one system. If your door is 12mm and wide, give us the panel weight and we will confirm the pivot rating.
Can the pivot hinge be adjusted after installation to level the door?
Pivot systems of this type normally allow fine adjustment at the pivot points so the installer can level the door and set the clearance after it is hung — glass doors almost always need small tweaks once the weight is on the pivots. Our install sheet covers the adjustment sequence. If your site has a specific adjustment need, mention it and we will confirm.
Is the pivot hardware 304 stainless throughout?
Yes, the pivot components are 304 stainless steel, chosen because the pivots sit in wet conditions and carry the door load. The finish — brushed nickel, chrome, brushed bronze, gun gray, or custom — is applied over the stainless base. A 316 option is available for coastal or chlorinated environments.
