Stone Pro has announced the release of an updated version of its popular SR2 Rail Support System.

“We have long heard from the stone industry how much nicer it would be if the SR2 had a rechargeable feature, rather than the AA battery power source,” said Bran Winn. And that is exactly what they did. 

Stone Pro’s engineers have come up with a rechargeable power system, and also managed to maintain the same footprint and basic cup design. An available, retrofit master cup will enable present owners of the SR2 Vacuum Rail Support System to convert their old unit over to the newer rechargeable version. 

“This can easily be done by simply sliding off the old Master Cup and on with the new. Replacing the standard cups won’t be necessary because those really haven’t changed, other than the color of the new series,” explained Winn.

“Even better, we have also incorporated the same power supply in the new SR2 that we use in the Seam Machine.

“That means that we can utilize the same power plant and recharging plug for both devices. It will be the same stock item for both devices. Same battery and same charging plug!”

The new SR2 Rechargeable eliminates the need for AA batteries, yet keeps its streamlined look. 

The second important upgrade is the SR2 is now made of a more durable black polymer. Beneath the rugged black housing of the “master cup” lies the new recharging system. “It adds a little additional weight to the whole unit,”said Winn, “But not enough to make a noticeable difference.”

The SR2 Rechargeable comes with its own charger, so there’s no need to worry if you’re on the jobsite and the power runs out. Simply plug it into an outlet and keep working. 

“Just like our previous model, we have also incorporated a safety relief valve for quick release and removal of the device, once your task is complete, said Winn. “The new version comes in a little bit heavier than the previous model due to the onboard battery, but the compromise is worth it.”

Features and benefits include:

  • Each SR2 has four adjustable suction cups connected in a series and is powered by a rechargeable master cup unit.
  • Each cup can be independently positioned by sliding the cup into the desired position.
  • Once the system is turned on, all cups will be actively vacuuming.
  • Cup covers are provided to protect the reversible vacuum seal during transportation. 
  • Simply charge the device (a minimum of) four hours prior to using.
  • A retrofit master cup (in white) is available for owners of the old system to upgrade to a rechargeable version.


The SR2 is designed to be used as a final installation tool. It is not recommended for use in very wet fabrication environments such as a wet shop, where water could cause damage to the vacuum pump.

The SR2 Vacuum rail is not intended as a slab support during mobile transit, but it excels when used for installation purposes, even on textured surfaces.
