Medical Cannabis Shop | Portland

Tree House Collective entrance with rooftop billboard and security spikes along the roofline

Project Overview

This project was carried out at a medical cannabis dispensary located just outside downtown Portland, North East Sandy Blvd. Cannabis shops often face elevated security risks due to their high-value inventory and cash-heavy operations. The store management sought a solution to protect the building’s perimeter—especially the roofline and vertical drainpipe areas that could serve as climbing points for intruders.

To address these concerns, Ninja Deterrent™ stainless-steel anti-climb spikes were installed along the roof parapet, combined with barbed wire around the upper section of the drainpipe. This created a strong, layered defense against unauthorized entry.


Installation Details

The installation was designed to blend with the building’s urban character. The spikes were mounted discreetly along the parapet edge, visible enough to deter intrusion but harmonized with the architecture and signage.

Layered Protection with Barbed Wire

This dual protection strategy makes it extremely difficult for intruders to scale the wall or use the drainpipe as a foothold.

Nighttime Security Presence

At night, the illuminated shop front draws attention to the defensive perimeter, sending a clear message of deterrence to potential intruders.

Outcome & Feedback

The management expressed high satisfaction with the results:

“Cannabis shops are always a target, and our location was no exception. With Ninja Deterrent™ on the roofline and barbed wire on the drainpipe, we feel much more secure. Customers notice the effort we’ve taken to protect the store, which also builds trust.”

Conclusion

This Portland installation demonstrates how Ninja Deterrent™ can be seamlessly combined with traditional security measures like barbed wire to protect high-risk businesses. For cannabis dispensaries, jewelry stores, and other retail spaces, this layered approach provides both physical resilience and psychological deterrence.
