Improve safety around extension ladders

Preventing falls when using extension ladders is essential. Each year, thousands of Canadians injure themselves by climbing an inadequately secured extension ladder. The Ladder stabilizer system prevents the ladder from sliding along the parapet and eliminates the need to secure it with a bungee cord or rope. 100% non-penetrating, the Ladder stabilizer system is a versatile equipment that adapts to all flat roofs.

Fall from non stabilized ladder

Stabilizes the Extension Ladder

No more risk of sliding. The extension ladder is stabilized by the hooks compatible with ladders with round or in “D” shaped rungs up to 2″ in diameter.

Guides the worker

The hoops offer a solid grip at the end of the ladder and the 10′ guardrail guide the worker towards the center of the roof.

Ladder stabilizer system for HVAC Maintenance

The Ladder stabilizer system is designed to make access to the roof safer during the maintenance of HVAC units. Because it installs quickly and without anchoring to the roof, the Ladder stabilizer system can be installed and left on the roof of the building permanently. The Ladder stabilizer system holds the extension ladder firmly in place and makes each visit to the roof safer.

Ladder stabilizer system for Construction Site

On a construction site, it is the responsibility of the general contractor to provide a safe access point to the roof for all subcontractors on the job site. The Ladder stabilizer system eliminates the time lost and wasted material associated with the fabrication of wooden railings at the exit of the ladders. Durable and reusable on all job sites, it adapts to all types of flat roofs and can be installed in a few minutes.

The Ladder stabilizer system (# LADPT2) is fitted with hooks compatible with ladders with round or “D” rungs up to 2″ in diameter. The hoops offer a solid grip at the arrival on the roof. The 10’ guardrail guide the worker toward the centre of the roof. The stabilizer only (# LADPT1) is also available. Contact us to determine which option is best suited to your situation!
