New old stock . Never used with 20 mm conduit entry. 2 way switch. No box It’s got the Delta logo on the back but basically it’s made by MEM. Built like a brick outhouse these last for years and years . The switch can be mounted with the conduit entry top or bottom. Ideally suited for use with quality outdoor lights such as Coughtrie etc. If you want a flex gland I will put one in but only if you ask at the time of purchase.
