Coil Forms



Inverted and external coils are available in a wide range of synthetic, natural and metal filaments, with and without brush holders, or can be installed with mounting tabs. Click here for available mounting tabs. Channel sizes include A, B, C, D, F, G and K and are available in galvanized and stainless steels. Minimum outside diameter (OD) and inside diameter (ID) depend on channel size and channel material as shown below.

Ez-Flex Strip Brush is available as an alternative to metal back brush. It's great for use around curves and in-field installation. Click here for more information.

If your application requires a coil form with diameter and radius less than those shown, contact a Sealeze Sales Representative for more information.
