Our Most Popular Shield for Lathe Chucks & Spindles

Ferndale Safety’s most popular lathe chuck shield

You can install it on conventional lathes, such as that old Monarch or Lodge & Shipley, that still works like a boss.  People love this guard because it’s lightweight and available in many sizes.


This lathe chuck shield includes a built-in electrical safety interlock switch.  The wiring is there – it is up to you if you want to connect it, but we highly recommend that you do.  Connect it to your motor control, and you will never forget your chuck key inside the chuck again.

You can change out your shield:

You will love how easy it is to replace a worn-out shield.  Pop out the used polycarbonate from this guard by removing the blue clips.  You can purchase replacement shields from us or cut your own from a polycarbonate sheet and slide it into the steel frame.  Simple as that.

What Screen Size is Best For Me?

To find what screen size you need for this lathe chuck shield:  Take the diameter of the biggest chuck you use on your lathe.  Multiply the diameter you measured by 1.5 and choose the screen size in A closest to your answer.  Using this formula will guarantee that you will have room under the guard even though the jaws are open beyond the diameter of the chuck.

Calculation Example

Chuck Size: 12″ in diameter by 6″ in width

Multiply 12″ by 1.5, and you get 18″.  The closest measurement for the A dimension to your calculations of 18″ is 17 3/4″.

Select 17 3/4″ from the “A” dimension drop-down box above.  Select 7″ from the “B” dimension drop-down box as it’s the closest to the width you measured.

Spare Parts

Easy Installation

Two-bolt installation:

Most of the time, you can drill and tap two holes directly into the headstock of your lathe.  On odd occasions, you might need to make some custom-made brackets.  We use aluminum angle stock, which is easy to work with and cut.  If you need any advice or help to install these lathe chuck shields, don’t hesitate to contact us; we will be more than happy to help you.

We can supply the installation hardware:

Installation hardware and tools are not included in this lathe chuck shield.  We offer a separate installation kit that contains the tools and equipment necessary to install this safety product.  You can buy the installation kit by clicking on the following link: Click here for the installation kit for this guard.

What is a Chuck Shield & why do I need it?

You need to guard the chuck on a lathe because:

The jaws can extend beyond the diameter of the actual chuck and can create an entanglement hazard.  These jaws could act as hooks, ready to grab onto anything more easily than a smooth shaft.


These shields prevent you from leaving the chuck key inside the chuck.

Here’s how:

This lathe chuck shield comes standard with an electrical safety interlock switch.  Connect this switch to disable the main motor when the guard is open.

Don’t forget:

The most common accident on a lathe is due to the chuck key flying across the room.

For this reason alone, we highly recommend installing this lathe chuck shield.
