An effective way to protect martins from large owls and hawks, allowing good martin house management. The guard pivots completely down out of the way to allow landlords access for monitoring.
An improved, re-engineered design, the OG1 can be installed on assembled houses, or added during assembly. Fits MSS12/TG12 (Trio Safety System/Grandpa) and M12K (Trio Musselman) houses only.
Instructions and hardware for mounting included. Each OG1 will protect an entire MSS12/TG12 or M12K house. Can be used with porch dividers.
