All of our glass doors come with a standard 2 5/8″ wide door frame. We strongly recommend not trying to match a cabinet and door to an existing piece of glass you already have on site. This will almost certainly result in a mismatch, requiring either a different door or having to cut the glass down to size.
Since we hand-route the wood door frames, there can be slight variations in the glass opening from one door to another. For best results, always order the cabinet in the size you need, then cut your glass to fit after the cabinets have arrived.
