The DTG-Adjustable Pedestal Support with Lumber Adaptor is used to connect standard wood profile or aluminum sub frame to the DTG-Adjustable Pedestal. You can install  2-2''x4'' or a 2''x6'' beam inside the space of the Lumber Adaptor.

Recommended spacing for the use of the pedestal with joist and 5/4'' lumber or composite material of 1'' net size. 

16''X48'' If you use a 2X4 or 2X6 on the strong side.

16"X24'' If you use a 2X4 or a 2X6 on the weak side 1.5'' side.

Note1: With some of the composite on the market you may need to space the pedestal every 12''

Note 2:  The spacing can be the same or greater for specialized wood such as IPE 5/4 or other thicker wood. However, it is important  not to exceed 8 square foot of load per pedestal.

NOTE: The DTG-Adjustable Pedestals  can sustain a lot of load. However, the weakest link rapidly becomes the roof membrane of your rooftop. If you don't have accurate data of your roof, we normally suggest to use 1 device every 2' in each direction. You can choose to screw them (if necessary) to the existing surface.

The total between hears of the lumber joist is 3- 1/16''

The Lumber joist head is 6-3/8''

 The pedestal head is 5-1/2''. the Lumber joist head is larger than the base pedestal head. For stability, load must be applied to the 5.5'' area under the main pedestal head.

 The pedestal base is 7-7/8''

****If you have a slope on your roof, we also offer the DTG-Slope Corrector, which allows for a much easier and even set up.
