The T5-J comes with J-bolt hardware. The T5-J will not work on I-beam or T-bar grating. The T5-L comes with L-bolt hardware. The T5-L will not work on grating with square opening. They both will work on all additional types of grating not mentioned above.

This will depend on the surface you are using it on. The T5-J will work on almost all grating that has vertical flat bars, either with square holes or rectangular openings. If you have I-bar or T-bar grating, you will need to use the T5-L. If you want to use them on solid flooring, such as concrete or deck plate, you may have to replace the hardware with anchors or threaded fasteners.

Not necessarily, assuming you have adequate beam support for the walkway grating.

Yes, but you may want to use threaded anchors in place of the J-bolts or L-bolts.

To help you in estimating and ordering, please refer to the table below.

No, not at all.  The links are designed to allow top-side installation.  Follow the directions and simply drop the J-bolts (L-bolts) down through the grating openings.

Yes, although the safety yellow color is normally acceptable for most purposes. The color is molded throughout the parts, so they should never need painting. However, if desired, the collar surfaces can be wiped clean and painted.

The only effect on the polyurethane material will be some surface discoloration to an amber shade.  Aside from this surface effect, the rest of the material does not lose any of its original strength or material properties when exposed to UV light.

• The maximum thickness of grating that can be “sandwiched” between the T5 and the J-bolt or L-bolt is 1 3/4″.
• If thicker grating is used, you will need to replace the standard hardware.

Yes! The T5 pieces can be combined to encircle just about anything (See answer to FAQ #5).

No, the T5 will not work with our previous GPC pieces.

Yes, the polyurethane material from which the links are molded is capable of supporting a load of over 2000 pounds in this fashion.
