M CLIPS (Fiberglass Grating Hold-Down Clips)

The M clip is the standard hold-down for fiberglass (FRP) grating. Its M-shaped saddle straddles two adjacent bars on molded or pultruded I-bar grating, and a bolt pulls the panel down tight to the support. The same saddle design is also used on steel bar grating. 316 stainless is the usual choice for FRP in corrosive service.

Typical Installation

Most FastGrate clips install from above with a standard wrench. No welding, no drilling, and no access needed underneath the platform. Once a two-person crew has the routine down, each clip takes about a minute.

Work out how many clips your platform needs or check the selection chart.

  1. Set the grating panel on its supports with the bearing bars spanning between them.
  2. Place the clip from above so it bridges the bearing bars and engages the support steel below.
  3. Tighten the bolt with a standard wrench until the clip sits snug against the grating and the support.
  4. Repeat at each clip location: at least four clips per panel, plus one at every intermediate support.

Frequently Asked Questions

How many M CLIPS do I need per grating panel?

Plan on at least four clips per panel, plus one at every intermediate support. That minimum comes from grating manufacturers' installation details. OSHA 1910.22 sets the performance requirement for secure walking-working surfaces rather than a clip count, so follow your grating manufacturer's detail or the engineer of record.

How long does it take to install M CLIPS?

About one minute per clip once a two-person crew has the routine down. There is no welding, so there is no hot work, no grinding and no touch-up of burned coatings.

What tools do I need?

A standard wrench. The clip installs from above, so the crew does not need access underneath the platform. Galvanized clips use grade 5 carbon steel hardware.

Which grating does the M CLIPS fit?

The M CLIPS fits Molded and pultruded (I-bar) fiberglass grating; steel bar grating. Sizes: Sized to grating depth and bar spacing. Send us your bearing bar depth and spacing and we will confirm the right clip.

Which material should I order for M CLIPS?

For fiberglass (FRP) grating, 316 stainless is the usual choice because FRP is typically specified for corrosive service. 304 stainless suits washdown areas. Galvanized works on steel bar grating in general industrial service.

Can I get free samples of M CLIPS?

Yes. Samples are free. Tick "Send me free samples" on the quote form or call us, and tell us which grating you are working with.
