Custom RV Shower Screen Door Widths | Elkhart RV Parts

For the custom-size order path, enter the measured finished opening width—37.5 inches in this example—rather than substituting a 48-inch standard width. The current Irvine shower-door builder separates “Custom Size — Built Fresh to Order” from its standard-size choices. The custom form accepts 37.5 in its width field. Enter the corresponding height and chosen finish separately, and check that the displayed dimensions and order type describe the intended configuration before ordering.

Record the finished opening width at the top, middle and bottom, along with jamb alignment, threshold shape and clearance for the cassette and latch side. Keep those measurements available if the opening is not square. An entered width is an order specification; it is not proof that every part of the finished assembly measures exactly that number or that the installation is a verified fit.

Order width, overall assembly dimensions and individual track cut lengths are different measurements. Irvine's Slow-Roll installation instructions include track fitting and trimming, with tracks engaging the cartridge and side-rail end caps. They do not establish that every custom order arrives requiring no adjustment, or that a particular 48-inch standard assembly may be reduced to this opening. Use the instructions and configuration supplied with the exact unit; do not infer a cutting plan from this answer.

Choosing a standard-size or cut-to-width configuration is a separate order choice that must match the selected product's stated preparation and installation requirements. The earlier assurance that entering 37.5 guarantees a precisely cut, ready-to-fit door was too broad. The custom width field records the requested opening dimension; final frame clearance, height convention and any required preparation still need to match the actual installation.
