The MONT-VentLock kit is a retrofit design for all current owners of the MONT/ Monticello Greenhouse. This allows for a quick release of the auto vent opener from the roof vent and a simple, quick lock system that will ensure that strong winds will not get into the greenhouse through the vents. THESE WILL ONLY WORK ON THE MONT OR MONTICELLO BRAND GREENHOUSE VENTS!! You can order these in multi packs as well. See features for a list of SKUs and pack sizes available. This is a set of 4 vents. Be sure to order enough for each roof vent your greenhouse has.
