What you need to know:
Expanding your 12 unit to an 18 unit gourd rack is not difficult. You will need to remove the pole from the ground stake. We recommend that when making this conversion you add the two-foot extension
to your existing 14' pole. We also recommend you consider upgrading your rope from its original 45' version to 55'
, especially if you add the Two-foot Extension Piece. When adding the extension, your rope will not be long enough, which you will notice when you lower your hub for nest inspections. This kit includes the Aluminum Gourd Arms found with the Deluxe 12
. Never do this conversion once martins have begun nesting.
