The H7ICTNB is designed for installations where the housing will be in direct contact with insulation. The H7ICTNB is designed to save installation time. It is designed without a socket plate for use with socket supporting trims only. With these trims there is no need to spend time removing the socket from the socket plate and the socket plate from the housing. H7ICTNB may be converted into AIR-TITE® installation when used with AIR-TITE® trims.
