Summit's unique selection of built-in cooking appliances brings all the features you need to compact kitchen spaces. The OTR24SS is a built-in microwave designed for enclosed installation above or below counters, with a front-venting design. We include a stainless steel trim kit that lets you frame the unit in stunning style. The nearly opaque door features a unique mirror finish and stainless steel handle for modern style that suits virtually any kitchen setting. 1-touch cooking options include settings for popcorn, pizza, beverages, frozen dinners and baked potatoes, with defrost options for speed or weight and a safety lock to help prevent unintended heating. The digital display also includes a timer function for added convenience and audible end of cycle alert. This microwave can be set for 2-stage cooking as needed to accommodate specific recipes. A removable glass turntable is included. The OTR24SS has an unfinished cabinet and must be installed inside a cabinet (recommended cutout is 13.8 in. H x 22 in. W x 16.2 in. D).
