TBT Restrictors

We often overlook the indispensable role that Tilt Before Turn (TBT) restrictors play in preventing your £500 window from becoming a £500 mistake. A TBT restrictor is a specialised safety device that controls the tilt-before-turn sequence, ensuring your window opens in the correct order every single time.

They’re clever mechanisms that act as mechanical gatekeepers. They prevent your window from turning fully until it has first been tilted to the ventilation position. Besides preventing operational miscues, TBT restrictors are essential safety features, especially in households with children or even upper-floor installations where improper opening could pose serious risks.

TBT restrictors also extend your window’s longevity. First, they correct operation. Moreover, they reduce wear on your window’s hinges and corner drives. As such, these devices are indispensable for window repairers addressing malfunctioning tilt and turn window systems. Property managers and even safety-conscious homeowners appreciate these restrictors, too.

At Locks & Handles we supply top-quality restrictors compatible with major European hardware systems, like Maco. Our TBT restrictors feature durable alloy construction. Their finish resists corrosion, making them ideal for high-humidity and coastal environments. Unsure which restrictor matches your Tilt-Before-Turn system?
