460-258-5400-k2-sgd-(1).jpg


The 5400 (K2) commercial vinyl sliding door system has been thoroughly tested to AAMA standards, achieving a LC-PG50 in multiple-panel configurations. It is manufactured with long-lasting, .100-inch thick-walled extrusions that will stand up to even the harshest weather conditions and wind loads. And since it’s PVC, it’s energy efficient and will never pit, warp, rot, corrode, peel or crack.

The K2 door’s design includes equal glass and sight lines and multi-chambered profiles for strong welds and maximum thermal performance. Narrow- and wide-stile design options are available. It can accept multiple glazing options, such as monolithic or insulated, and utilizes a variety of hardware options. It is also available with add-a-track extenders.

The K2 5400 Series Patio Doors are offered with optional patent-pending SuperCapSR™ exterior color coating designed to prevent profile distortion from high outdoor temperatures and provide long-lasting, vibrant color.
