MAD Cowl Terracotta Bolt Fix

Product code: B16837


The MAD cowl is the most popular compact anti downdraught cowl on the British market. The reasons for this are that its compact and aerodynamic shape allows it to combat downdraught. Alongside this, the MAD cowl features a drainage system designed to divert rainwater away from the pot when in use, whilst the internal stainless steel birdguard prevents birds, leaves and vermin entering the chimney. As with all MAD cowls, the quality on offer surpasses that of equivalent inferior models being offered elsewhere.
