Accuracy is everything on site. When measurements are even slightly off, the quality of the job suffers. That’s why Stabila developed Locked Vial technology – an innovation that redefines how a spirit level stays accurate over its lifetime.
What Makes the Locked Vial Different?
Traditional spirit levels can lose accuracy over time as the vial shifts or the housing weakens. Stabila solves this problem with a unique assembly process where the vial is cast directly into a specially engineered block holder. This holder is then bonded into the aluminium profile in a way that makes movement impossible.
Because the vial is locked in position without any stress, it stays perfectly aligned with the measuring surface-permanently. This isn’t just a claim; it’s a technology proven to keep your level as precise years down the line as it was the day it left the factory.
Permanently Bonded for Lifetime Accuracy
The Locked Vial system uses a special casting process to bond the components of the spirit level forever. Unlike conventional levels where parts can loosen under site conditions, Stabila’s design creates a single, solid unit where nothing can shift.
This permanent alignment guarantees consistent accuracy, even when your level takes the daily knocks, falls, and extreme conditions of construction work. Simply put, it’s a spirit level you can rely on for life.
Built to Withstand Harsh Conditions
Construction sites are unforgiving, but Stabila Locked Vials are tougher than the challenges you face. The vials themselves are resistant to extreme temperatures, maintaining perfect readings from -20°C to +50°C, and the robust aluminium profiles protect the assembly under heavy strain. The result is a tool that performs faultlessly, even when the environment doesn’t.
Confidence Backed by a 10-Year Guarantee
Stabila is so confident in this technology that every Locked Vial spirit level comes with a 10-year guarantee. This isn’t just about selling a tool – it’s about giving tradesmen total peace of mind that their level will never let them down.
Final Verdict
With Locked Vial technology, Stabila has created more than just a spirit level. They’ve engineered a tool that sets a new standard for accuracy and durability on site. For tradesmen who refuse to compromise, there’s no better choice.
