Back to Self Closing & Manual Windows


Similar to the BPSC-4836, this manual bi-parting, self-closing slider is a smaller version of the BPSC-4836 in that the width has been narrowed to 42”. The height remains the same so that we can still offer a generous service opening of 14” (w) x 28 1/2” (h). This window is made for businesses that have much smaller work areas to contend with and allow the business versatility of not having to cut a larger hole to use a standard 48” wide window. This window also has a nice inside counter space for staging product.


Service Opening: 14”(w) x 28-1/2”(h)
Rough Opening: 42-3/8”(w) x 36-3/8”(h)
Counter Space: 42”(w) x 5”(d)
