Thanks for contacting Tundra Restaurant Supply, we're happy to help with customer questions. I've talked with Imperial regarding a "mounting kit" for the ISB-36 Salamander Broiler and they gave me two possible mounting options. I'm hoping one of them is the answer you're looking for! Imperial product # 14060 is a reinforcement kit that let's you attach the unit to the back of a range. Imperial product # 14056 is a wall mounting kit for the unit. Feel free to give out friendly sales team a call at 1-888-388-6372, and they'll be happy to order either product for you.
