Grade 1 Cylindrical Locks

XGT Series

The XGT Series super heavy duty grade 1 Cylindrical lock is the strongest in the industry. Designed to withstand over 3,000 in-lbs of lever torque resistance, it will outperform all other locks in the highest use and abuse openings.

Strength and Endurance are what make a great lock and that’s where the XGT excels.

Our innovative cylindrical lock design eliminates the need for additive clutching parts to improve strength. Our engineers thought: “Why add a band-aid (a clutch) when we can design it right the first time?” (Note: all our competitors used a clutch to add strength. We thought we could do better and we did.) That’s why it’s perfect for high-use, high-abuse applications like K-12 schools and universities.
