T-handle knobs offer an ergonomic and effective control mechanism. Like other types of industrial knobs, they are commonly used to adjust machinery and equipment. T-handle knobs, however, feature a unique T-shaped design that makes them easy to grab and turn. Here are several important things to consider when choosing a T-handle knob.
#1) Locking vs Non-Locking
T-handle knobs are available in locking and non-locking styles. Both styles feature the same T-shaped design. The difference is that locking T-handle knobs can be locked in place with a key. After engaging the lock, you won’t be able to turn the knob. Locking styles are a popular choice for doors and access panels because of their ability to control access.
#2) Material
You can find T-handle knobs in different materials, such as phenolic, technopolymer and thermoplastic. Phenolic is a type of thermosetting resin. It’s created by mixing phenol with various chemicals, which causes it to cure and harden. Technopolymer is a type of high-performance plastic that’s prized for its high strength-to-weight ratio and chemical resistance. Thermoplastic is a type of polymer that becomes soft when heated and hard when cooled. Regardless, you can’t go wrong with a T-handle knob made of any of these materials.
#3) Size
Don’t forget to consider the size when choosing a T-handle knob. There’s no one-size-fits-all option. Rather, some people prefer a large T-handle knob, whereas others prefer a smaller knob. Large knobs can be easier to grab and turn, but they also take up more space. If clearance is a concern, you may want to choose a smaller knob.
#4) Tapped vs Stud
T-handle knobs can be classified as tapped or stud depending on how they are installed. Tapped knobs have a threaded insert. You can install them by twisting them onto a threaded rod. Stud knobs, on the other hand, have a threaded rod or stud built into the base. You can install them by twisting them into a threaded hole.
#5) Finish
Something else to consider when choosing a T-handle knob is the finish. The finish is the outer layer. It enhances the aesthetics of the knob and, in many cases, improves the knob’s durability and longevity. Common finishes for T-handle knobs include powder coating, brushed, matte, glossy and semi-glossy.
#6) Load Rating
Some T-handle knobs are load-rated. As the name suggests, this represents the maximum of force the knob can safely handle. It’s typically measured in Newtons. Some T-handle knobs have a load rating of 2,500 Newtons, whereas others have a load rating of up to 4,500 Newtons.
