Need Some Help?
How do I size a machine guard?
See our machine guard sizing worksheets for instructions on how to measure for a machine safety guard or cover.
Why use a plastic machine guard or cover?
In addition to being lightweight and durable, there are many plastic machine guard advantages.
How do we set up an account?
We need to see three good credit references. You can speed up the process by sending credit references with or before an initial order. Our standard terms are net 30 days upon approval of credit references. We accept Visa, MasterCard, American Express and Discover cards.
What kind of prints or drawings do you need to tool a custom part?
We have made tools from simple hand drawn sketches, and still can for simple projects. For more complex projects we prefer working with solid models in IGES or STEP format.
Are your guards OSHA approved?
OSHA does not approve guards. Our guards and other products, if installed correctly, meet OSHA requirements for most applications. For more information see OSHA Machine Guarding Standards.
