With this Coupler you can upgrade your existing nests!
 You don't need V1 or V2 for this, it can be applied to your existing nests that you already have.
 There are two screws that ensure it's completely secured to your nest. This means you no longer have to worry about it coming loose while lifting if you ever want to move your setup.
 The acrylic tube is 15mm on the outside and 11mm on the inside so more than enough room for your ants to walk past each other.
 It is more beautiful and sturdier than an acrylic hose.
 We also have T - L and Y connectors.
 If you have a V1 outdoor unit with the connection located under the floor, you'll also need a 15mm outdoor unit connector.
