Product availability: Fiberr does not currently sell
grating clips. However, we can assist customers in identifying and
selecting an appropriate clip type for their grating, supporting
structure, and installation requirements.
Fasteners are essential components for securing molded FRP grating
assemblies. They anchor panels to the supporting structure and, where
required, connect adjacent panels to improve alignment and stability.
Proper fastening is particularly important in pedestrian-accessible
areas, elevated installations, high-vibration environments, and any
application where panel displacement could create a fall, trip, or
equipment hazard.
Installation guidance: As a general best practice, each
grating panel should be secured at all four corners. Additional fasteners
may be required along intermediate supports, panel joints, perimeter
edges, or high-load areas based on panel size, span, vibration, traffic,
wind uplift, and the supporting structure.
Available Fastener Types
C-Type (End Panel) Clip
The C-Type end panel clip is primarily used to connect two
adjacent molded grating panels. The opposing clip sections engage
the load bars on each side of the panel joint and are tightened
together with a bolt.
Connecting adjacent panels helps maintain alignment, reduces
differential movement, and minimizes uneven panel edges at the
joint. C-Type clips supplement panel-to-support hold-down clips
but do not normally replace them.
Common Applications
Panel-to-panel joints
Large floor assemblies
Long walkways
Multi-panel platforms
Alignment control
Primary function: Joins the ends or edges of two
adjacent grating panels.
E-Type (Small Mesh Hold Down) Clip
The E-Type hold-down clip is designed to attach 0.75-inch mesh
molded grating to supporting structures. Its compact profile is
configured for smaller mesh openings where a conventional
saddle-style clip may not fit properly.
The clip should be selected to match the grating mesh, panel
depth, supporting-member geometry, required bolt length, and
installation access.
Common Applications
0.75-inch mesh grating
Minimesh grating
Small mesh openings
Pedestrian flooring
Panel hold-down connections
Primary function: Attaches 0.75-inch mesh molded
grating to the supporting structure.
F-Type (End Panel) Clip
The F-Type end panel clip is used to connect adjacent molded FRP
grating panels. It engages the adjoining panel edges to help
maintain alignment and reduce differential movement at the panel
joint.
A fastening bolt is included with the clip order. F-Type end
panel clips supplement the clips used to secure each panel to the
supporting structure and should not normally be used as a
substitute for panel hold-down clips.
Common Applications
Adjacent molded FRP panels
Panel edge connections
Multi-panel platforms
Walkway panel joints
Panel alignment
Primary function: Connects adjacent molded FRP
grating panels. A fastening bolt is included with the clip order.
L/J Type Clip
The L/J Type clip is used at panel edges and perimeter locations
where an M-Type saddle clip cannot bear across two adjacent load
bars. Its angled or hooked profile captures a single edge bar
while the lower portion connects to or hooks beneath the
supporting structure.
This clip provides a low-profile edge connection and is
particularly useful where the grating terminates beside a wall,
frame, curb, structural angle, channel, or other obstruction.
Common Applications
Panel perimeters
Edge load bars
Wall interfaces
Angle or channel supports
Restricted-access locations
Primary function: Secures an outside panel edge
to or beneath the supporting structure.
M-Type (Saddle) Clip
The M-Type saddle clip is a common hold-down option for molded FRP
grating installations. Its saddle-shaped upper plate bears across
adjacent load bars while a bolt connects the plate to a lower
anchor, support clip, or drilled structural member.
The M-Type clip provides clamping pressure across the grating
bars, straightforward installation, and relatively easy removal
when access beneath the grating is required.
Common Applications
Standard molded grating
Industrial walkways
Platforms
Trench covers
Pedestrian flooring
Primary function: Secures a grating panel to the
supporting structure.
W/WLP-Type (Washer) Clip
The W/WLP-Type washer clip uses a broad, washer-like top plate
that spans several closely spaced load bars. The wider bearing
surface distributes clamping pressure over a larger portion of
the grating than a conventional M-Type saddle clip.
It is particularly useful for minimesh, micromesh, closely spaced
mesh, and some covered-grating configurations where the openings
are too small for a standard saddle clip or where a wider
pressure-distribution plate is preferred.
Common Applications
Minimesh
Micromesh
ADA mesh
Covered grating
Small mesh openings
Primary function: Provides a wide-area hold-down
connection for small-mesh and covered grating.
Wedge Type Clip
The Wedge Type clip is an internal clip designed to fit within a
molded grating mesh opening. Its formed sides engage the tapered
load bars and lock beneath the wider lower portion of the molded
bars.
Because molded grating load bars generally taper from a narrower
upper surface to a wider base, the clip develops a mechanical
grip inside the mesh without requiring a broad saddle plate
across the top.
This creates a low-profile connection with minimal hardware
projecting above the walking surface. Compatibility depends on
the specific mesh opening, panel depth, load-bar taper, support
configuration, and clip dimensions.
Common Applications
Low-profile installations
Internal mesh fastening
Tapered molded bars
Restricted top clearance
Specialty grating assemblies
Primary function: Locks within the molded mesh
opening by engaging the tapered load bars.

Multi-panel walkways, platforms, and floor assemblies
Supplements, but does not replace, panel-to-support hold-down

Inspection and maintenance: Clips and associated hardware
should be inspected periodically for looseness, corrosion, deformation,
missing hardware, support movement, and panel wear. Inspection frequency
should reflect the application, vibration, traffic, environmental
exposure, and consequences of clip failure. Replace damaged or
significantly corroded hardware promptly.
