Our take on the Prime-Line 1/2 in Glass Shower Door Vertical Side Seal

This is a clear vinyl vertical side seal that fits 1/2-inch-thick frameless swing shower doors. It slides onto the door's vertical edge to close the gap against the wall or a fixed panel and to keep water from escaping onto the floor. It is a small, low-cost wear part rather than a full door component, so it suits anyone replacing a cracked, yellowed or missing seal on an existing frameless door. Compared with generic peel-and-stick sweeps, a rigid slide-on seal holds its shape better and is easier to align, but it only fits doors of the stated glass thickness.

Questions and answers

Will it fit my frameless shower door?
It is made for doors with 1/2-inch-thick glass. Measure your glass thickness first; thinner doors need a different seal.
Does it need adhesive or drilling?
No. The seal slides onto the vertical glass edge and holds by friction, so no glue or screws are needed.
Can I cut it to length?
Yes. Trim it with a utility knife or heavy scissors to match your door height.
Is this the same as a bottom sweep?
No. This is a vertical side seal for the door's edge. The bottom sweep is a separate part that seals against the threshold.
Will it stop all water leaks?
It closes the vertical gap, but leaks from a misaligned door, worn hinges or a missing bottom sweep need those parts fixed too.
How do I clean it?
Wipe it with mild soap and water. Avoid harsh solvents, which can cloud or harden the vinyl.
