Tie Down PX2 Hybrid Mobile Fall Protection Cart, Spike or Concrete Anchoring
The PX2 Hybrid is the small crew Penetrator with two ways to hold. On membrane roofs its steel spikes engage the deck under fall load like the PX3 and PX5. On concrete it switches to a concrete attachment, so one cart covers the TPO roof and the concrete deck on the same project.
At 643 lb it anchors three workers on spikes, two in fall arrest and one in restraint, or two workers on concrete, one in fall arrest and one in restraint. It is the entry point to the Tie Down penetrating line for maintenance crews and small contractors who rarely put more than two people at the edge.
The finance payment shown is a sample, not an offer. Financing is provided through APPROVE and its lender network, subject to credit approval, at a 60 month term; your offered rate and term may differ. Financing is available on single items priced at 1,500 dollars and up, including smaller items bundled with the unit.
Who Needs This Product
The PX2 Hybrid is for building maintenance teams, small roofing and mechanical contractors, and facility owners who need a mobile anchorage for one or two workers in fall arrest and want it to work on both the membrane roof and the concrete deck. Each worker needs a harness, a connecting device sized to the setback, and a rescue plan.
Features
Two anchoring modes
Steel penetrator spikes for TPO, EPDM and built-up roofs, or the concrete attachment for smooth concrete decks. Change modes per the Tie Down instructions.
Three workers on spikes
Two fall arrest and one fall restraint connection on membrane and built-up roofs.
Two workers on concrete
One fall arrest and one restraint when set up with the concrete attachment.
Lighter than the PX5
At 643 lb it is a simpler crane pick than the 1,069 lb Sentinel for crews that do not need seven tie-offs.
Penetrator family hardware
Same red fall arrest connection points, flat-free tires and hoist rings as the rest of the Tie Down cart line.
Ships job site ready

Typical Applications
How to Use
Follow the Tie Down instruction manual. The sequence below is an overview only.
- Choose the mode. Spikes for membrane and built-up roofs, concrete attachment for smooth concrete, per the Tie Down instructions.
- Verify the surface and load. Confirm the surface is approved, slope 1:12 or less, and the deck carries 643 lb plus the crew.
- Hoist and position. Lift by the hoist rings and roll the cart to the setback stated in the manual, square to the edge.
- Connect. Two fall arrest and one restraint worker on spikes, or one fall arrest and one restraint on concrete.
- Reposition. Keep restraint lengths shorter than the distance to the edge while rolling to the next position.
Inspection and Retirement
Inspect before each use, with a documented competent person inspection at least annually. Remove the system from service for any of the conditions below.
- Spikes, concrete attachment and mechanism: bending, cracks, corrosion or binding.
- Tie-off points and hoist rings: distortion, cracks, worn pins.
- Frame and welds: cracks, bends or corrosion.
