You have to drill holes or melt holes with a soldering iron. I think that is true of any of them. These racks come with flexwatt installed as well. I dont know where you are in Canada but Natures Spirit is at the Taylor Michigan (Detroit) reptile show the 2nd Saturday of every month and if you order ahead online you can pick them up without the shipping cost and they are more than reasonable.If you email them they would give you a prompt response about shipping cost to you.
