PARAPET GUARDRAILNo ballast neededMODEL GUP2X4

Frontline GUP2X4 parapet guardrail questions answered
How does the GUP2X4 attach to a parapet without ballast?
It clamps directly to the existing parapet wall and raises the protected height to code — no ballast to hoist, stage or trip over.
What rails does the GUP2X4 parapet guardrail use?
Standard 2x4 lumber, which is cheap, replaceable and available anywhere; the clamps and posts do the structural work.
How many GUP2X4 posts do I need for my parapet?
Pricing is per post, so the system scales to any roofline — space the posts per the manufacturer’s instructions and your rail length.
Is the Frontline GUP2X4 parapet guardrail CSA certified?
No. Frontline rates it to OSHA 1910 and 1926; it is a structural guardrail product, not CSA Z259 PPE — confirm the assembled rail height and loads against your provincial code for your parapet condition.
