Guide Block: A block that is installed at the bottom of a shower/tub door that guides or keeps a sliding door in-line with either the stationary panel or another door. 

Guide Rail: A track or rail designed to control the movement of an object, such as a door. Top or bottom part of the sliding shower door or enclosure structure that provides support and/or acts as a track for the roller wheel assemblies for sliding shower door models. 

Hardware: Any component used to assemble and/or support the shower door. 

Hinge: A pivoting mechanism that allows a glass door to swing open and closed, available in various styles (e.g., pivot, wall-mount).

Header: A horizontal metal bar installed at the top of a shower enclosure to provide additional support for glass panels.

Hinge Side: The side of the door where the hinges attach. 

Impact Resistance: The ability of materials (usually glass) to withstand force or impact without breaking or shattering.

Inline panel(s): A glass panel directly beside and on the same horizontal plane as the shower door. 

Integrated Glass Shelves: Provides additional support to stabilize a stationary panel, preventing it from vibrating when opening and closing the shower door. 

Jamb: The vertical sides of a door frame or opening where doors or panels are hinged or secured

L-Bracket: A bracket shaped like an “L” that provides support for a stationary panel. It attaches to the wall and to the top of the stationary panel glass. 

Neo-Angle: A corner shower configuration with three glass panels forming a diamond-like shape, ideal for small bathrooms.

Notched Panel: A stationary glass panel with a cutout, usually to accommodate a tub deck or buttress. 

Opening Width: The total space available for door entry, which determines the appropriate door type and size.

Out-of-Plumb: Any surface condition with greater than 1/16” out-of-vertical line or out-of-square. 

Pivot: A supporting system for a swing door where the rotating mechanism attaches to the top and bottom of the door. 

Pivot Bars: A top and bottom bar installed at the door opening that stabilizes the panels and attaches the top and bottom door pivot system. 

Pivot Door: A shower door that rotates on an axis by two metal pins that pivot on the top and bottom of the door. The weight of the door is supported by the bottom pivot while the top pivot acts as a guide. 

Plumb and Level: “Plumb” is the measurement of the vertical level and “Level” is the measurement of the horizontal level. The level’s “bubble” must be centered between the lines in the vial to be considered plumb or level. 

L-Bracket: A bracket shaped like an “L” that provides support for a stationary panel. It attaches to the wall and to the top of the stationary panel glass. 

Return Panels: Stationary panels that are installed at 90deg or 135deg in relation to the door. Secured in place with support bars, wall profiles or wall brackets, and bottom brackets. 

Rough Opening: Preliminary measurement between unfinished walls or studs usually referenced for shower base or back wall installation. 

Seal Strip: Any plastic strip used to prevent a shower enclosure from leaking. Attached between doors and panels, between the door and the wall, beneath the door and the sill, etc. 

Semi-Frameless Glass: Frameless door glass that is hung with perimeter framing only (i.e. Flex, Infinity, Duet, etc.) 

Shower Base (aka Shower Floor, Shower Pan, Shower Tray): Part of the shower where you stand. Serves as the water basin for water to drain. DreamLine bases are made from sturdy acrylic and fiberglass reinforcement. 

Silicone Caulk: A translucent caulk product used to seal the edges and seams of shower enclosures. Its main function is to prevent leaking. Some silicone products have a mildew-resistant additive to keep it clean and relatively transparent over time. 

Stationary Panel: A fixed panel of glass that does not move, open, or close.

Sweep: The strip that snaps onto the bottom of a door panel and seals the space beneath the door, also deflects water cascading down the door glass back into the shower or tub. 

Tempered Glass: Heat-strengthened glass that has a safe breaking pattern. A rapid heating and cooling process makes tempered glass four times stronger than non-tempered glass. Once a piece of glass has been tempered, it cannot be cut. In the event of breakage, tempered glass fractures into small particles which do not form sharp edges. All DreamLine tempered glass is ANSI Z97.1 certified.
