What Homeowners & Installers Say
"Installed this around my DIY MrCool mini split line set. The original hole through my brick wall looked awful with silicone caulk peeling off. This plate covered everything up and made it look like a pro installed it!"
"We had wasps trying to nest in the wall hole behind our outdoor heat pump. This cover plate sealed the gap tightly with the foam strips. Haven't seen a single bug inside since!"
"As an HVAC technician, I keep a few of these kit boxes in my truck. Customers love how clean the exterior wall looks after we finish the job. Highly recommended!"
