If you know your model number we will never ask you for dimensions: we already know the dimensions of your equipment. Since 1975 we have worked closely with OEM engineers, sales, marketing, and parts departments to maintain and develop current patterns for every make, model and year of air conditioner.
When a manufacturer introduces a new air conditioner model they will contact Brinmar and send us technical literature. We will then measure the equipment in the field, or have the manufacturer send us their equipment for measurements. Samples are then made with several fittings in order to ensure accuracy of a pattern. This is why our products always fit perfectly.
