What size cradle should I choose
This depends on the height of the joist that you have. The 10-25mm cradle is usually used with the 22mm joist which gives the height build up of 32-47mm from the ground/roof surface to the underside of your deck board. For the 10-40mm cradle, we usually use a 38mm joist giving 48-78mm buildup and for the 10-55mm, we use the 72mm joist giving a 82mm-127mm buildup.
