# Straight-Line (180°) Shower Door Seals & H-Jambs | IDEAL Shower Doors URL: https://idealshowerdoors.com/store/c/inline-180 Description: Seals for where a glass shower door closes in a straight line against a fixed glass panel or a wall: H-jambs, Y-jambs and multi-purpose H wipes for 1/4" to 1/2" glass. Seller: IDEAL Shower Doors, Danvers, MA (https://idealshowerdoors.com/store/) --- 22 products # 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](https://idealshowerdoors.com/store/measure) 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.

The most popular for 3/8" glass is the clear polycarbonate 'H' jamb (part [P380HJ](https://idealshowerdoors.com/store/p/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](https://idealshowerdoors.com/store/p/p375hw) (or [P375HWS](https://idealshowerdoors.com/store/p/p375hws) with extra-soft legs). Stick-on [bulb seals](https://idealshowerdoors.com/store/c/bulb-fin) 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](https://idealshowerdoors.com/store/c/bulb-fin) 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. Seal Finder ### Tell us where it leaks. We'll tell you what fits.
