Straight-Line (180°) Shower Door Seals & H-Jambs
When a frameless door closes in a straight line, either into a fixed glass panel beside it (a 180° inline layout) or against a wall, the vertical gap along that edge needs a seal. These seals pressure fit onto the edge of the glass and either overlap the gap with a rigid lip or close it with a soft leg.
Our installers use the multi-purpose 'H' wipe constantly: on the edge of a door that closes against a wall, on the hinge or pivot side against the panel that supports the door, and between a door and a fixed panel.
How to choose
- Match your glass thickness exactly.
- Door closes into a fixed glass panel: an 'H' jamb (rigid, clear, low-profile) or a 'Y' jamb (soft leg for a quieter close).
- Door closes against a wall, or you need to seal the hinge side: a multi-purpose 'H' wipe.
- Want the strongest seal against leaks on an inline door: a heavy-duty 'H' jamb with a vinyl insert.
- Most of these seals suit a gap of about 3/16" between door and panel.

Common questions
What seal goes between a glass shower door and a fixed panel?
For a door that closes in a straight line into a fixed panel, use a 180° 'H' jamb or 'Y' jamb that pressure fits onto the edge of the fixed panel. The most popular for 3/8" glass is the clear polycarbonate 'H' jamb (part P380HJ), suggested gap 3/16".
What seal do I use where a glass shower door closes against a wall?
A multi-purpose 'H' wipe pressure fits onto the edge of the door, and its soft legs seal against the wall. For 3/8" glass that is part P375HW (or P375HWS with extra-soft legs). Stick-on bulb seals that tape to the wall are another option.
How do I seal the hinge side of a frameless shower door?
On the hinge or pivot side, a multi-purpose 'H' wipe on the door edge seals against the panel that supports the door. Stick-on bulb seals mounted to the glass edge or wall also work well on the hinge side.
What is the difference between an H jamb and a Y jamb?
An 'H' jamb is all rigid polycarbonate with a lip that overlaps the gap. A 'Y' jamb has a rigid clip with a soft vinyl leg that cushions the door, so it closes more quietly.
