SkyJack SD-EXT Extender Sleeve – Add Height to SkyJack Adjustable Pedestals with Confidence

The SkyJack SD-EXT Extender Sleeve is the ideal solution for extending the height range of your SkyJack SD-XL adjustable pedestals. Designed for rooftop paver systems that require added elevation, the SD-EXT quickly and securely screws into the base of your existing SD-XL pedestal, increasing total height without compromising stability or performance.

Built from the same high-strength, weather-resistant polypropylene as the full SkyJack pedestal line, this 8″ extender sleeve can be stacked (up to 3 extender sleeves on top of each SD-XL adjustable pedestal) to achieve pedestal heights up to 37.75 inches—making it the go-to option for accommodating slopes, drains, parapet transitions, or elevated decking platforms.

Key Features:

• Adds 8″ of height to the SkyJack SD-XL pedestal (this product is not a standalone part.  It must be added on top of the SD-XL pedestal)

• Stack up to 3 extenders for total height up to 37.75″

• Threaded design ensures secure, wobble-free installation

• Made from durable, UV and weather-resistant HD polypropylene

• Ideal for rooftop decks, terraces, and sloped installations

• Recommended with SkyDeck’s SkyHeights Stabilization System for added support above 21.75″ (*contact our staff for more information on our stabilizing system for pedestals over 21.75″ tall)

For taller rooftop paver systems, the SkyJack SD-EXT delivers the height you need with the strength and stability you trust.

Compatibility:

Extender sleeves are compatible with the SD-XL Adjustable Pedestals.  Add up to 3 extenders onto each SD-XL adjustable pedestal.

Q: How can I determine what pedestal heights I need?
A:  Your threshold will set the height of your entire patio.  You will need a stringline or laser level.  Take measurements from the finished roof up to the line at every high and low point on the roof.  Send us those measurements and we will do the rest!

Q:  Can I install a paver pedestal system myself or do I need a contractor?
A:  It depends.  Our pedestal paver system is designed to be very simple to use.  Many homeowners can install it themselves.  The toughest part is cutting your flooring material to the right size along the perimeters.  If you feel confident doing that, the installation should be a breeze.  Our staff is always available to answer questions or do a video call to help with any installation issues that you may run into.
