Everything You Need To Know About Auto-Lock Tape Measures


Tape measures are one of the most powerful tools that you can have in your toolbox. They may not be as high tech as laser-guided table saws or a power drill, but you won’t be able to complete a project without one.

In fact, auto-lock tape measures are Keson’s fastest-growing specialty series. With a range of world-class features such as nylon-coating, rubber grip and a 3-rivet hook, these tapes are the complete solution for all your measuring needs.

Different Features Of Auto-Lock Tape Measures


Simply put, auto-lock tape measures are an innovative makeover of the common measuring tape: high on convenience, comfort and quality.

But before you invest in one, here is a list of features that you should look for.



Automatic, Button-Release Lock

An automatic button-release lock makes it convenient for you to use the blade without having to adjust the lock again and again.

The lock engages automatically and allows the blade to stay out until you press the release button, which then disengages it and allows it to retract easily.

Nylon Coated Steel Blade

Nylon is one of the most popular materials when it comes to coating; it provides a plethora of benefits that extend the life of the measuring tape.

That’s why high-quality tape measures — such as Keson’s — that come with a nylon coated steel blade are perfect for construction workers, architects, plumbers and maintenance staff who work long hours in the sun.

Additionally, nylon coating eliminates the risk of premature wear and tear due to excessive use and protects against water damage.

Heavy-Duty End Hook

The hook end tab is attached at the end of the measuring tape. This is a flat, 90-degree angle hook designed to prevent the measuring blade from sliding back into the reel case before you’re ready to release it.

Keson’s range of auto-lock tape measures come with wide, heavy-duty end hooks that speed up construction work and allow you to take accurate measurements.

Chrome Plated

Chrome plating improves the ‘wear and tear’ threshold of the tape measure. For example, Keson’s auto-lock tape measure comes with premium quality chrome plating that adds to its sturdiness and makes it corrosion-resistant.

Rubber Grip

Auto-lock tapes also come with a durable, high-visibility rubber grip that protects the blade and provides extra control to the user through its non-slip feature.

Easy-To-Read Graduations

Auto-lock tape measures have easy to read graduations and numbers; this allows professionals to take accurate measurements, even in less than ideal conditions, such as low light.

Belt Clip

Contractors, architects and plumbers are always on the move, getting work done on their construction sites. A good quality auto-lock tape measure comes with a belt clip which makes it easier for professionals to carry it around.
