OVERVIEW

OVERVIEW
The ClickFit mounting system consists of patented adjustable tile hooks and L feet, rails, and
the installation materials required for the mounting of photovoltaic modules on composition
shingle or tile roofs. For simplicity, tile hooks and L feet will be referred to as “attachments”.
ATTACHING TO THE ROOF
The attachments are fastened to the rafters. Attachments are height-adjustable to level the
system on uneven roof surfaces.
ATTACHING THE RAIL
The rail assembles to the attachments with a click-connector, or Clicker. The rail simply clicks
into place without the use of any tools.
ATTACHING THE MODULES
The modules are attached to the rails by means of mid clamps and end clamps.
Installer must review module and any 3rd party manufacturer’s documentation for
compatibility and compliance with warranty terms and conditions.
WARNING: This product must be installed and used according to this written instruction.
Any installation or use of this product not in accord with or not authorized by this written
instruction shall void any and all warranties, express or implied, on the product or the use
of the product and may cause failure, property damage and personal injury. EcoFasten is
not liable for any unauthorized use. Install and use only with other EcoFasten products to
ensure proper t and function.

ARRAY LAYOUT
• Refer to span tables, local jurisdiction, or engineer of record specications when determining
setbacks from roof edges, attachment spans, etc.
• Mark the perimeter and corners of the array on the roof surface.
*Add 3/4” to account for the gap between modules in each direction*
• Draw or snap chalk lines where the rails will be installed,(refer to module manufacturer specs
to determine allowable mounting locations).
• Locate rafters within the area of the array. It may be necessary to shift
the array East or West on the roof in order to fall within the rail cantilever
specs (1/ 3 of span).
• Stagger rafters every row if required by the local jurisdiction, engineer of record, or company
policy.

PRE-INSTALLING RAIL SPLICES
1. Determine the number of rails required per row of modules.
2. Insert a rail splice into one rail. Do not push it past the center bump.
3. Slide the next rail onto the rail splice until the two rail ends meet.
4. Repeat steps 2 and 3 until the desired length is achieved.*
*This is usually easiest to do from the ground.

INSTALLATION OF FLASHING & L-FOOT
• ClickFit for comp shingle roofs uses EcoFasten GF-1 watertight
ashing system.
• Other roof types may use dierent EcoFasten Solar
attachments, visit ecofastensolar.com to learn about other
applications.
INSTALLATION STEPS:
1. Locate rafter lines.
2. Drill 7/32" pilot holes at all attachment points and back ll using roof-compatible sealant.
3. Separate shingles where ashing is to be installed. Insert the ashing so the top portion is under
the next row of shingles north of the pilot hole. Ensure the ashing is pushed to the third-course
of shingle to prevent water inltration through the vertical joints between shingles.
4. Align GF-1 ashing hole with pilot hole. Insert the lag bolt with pre-installed bonded washer
through the L foot and EPDM grommet. Tighten the lag bolt until fully seated. The EPDM Ring
visual indicator is the most eective way to ensure a watertight seal.
*Note the orientation of the L foot and clicker.
The clicker should be facing downslope

INSTALLING TILE HOOKS
1. Locate rafters on the roof, mark the tiles to be removed. Hint: In some cases rafter tails are visible at
the eaves of the roof, making it easy to nd the rough location of the rafters. In other cases, the fascia
board may have nail heads visible where it was attached to the rafters. In the worst-case a row of tiles
may need to be moved to determine the rafter locations.
2. Slide the tile at the desired location upward to expose the roof sub surface. If the tile is to be notched,
or if using a replacement ashing, remove it entirely. Clean the sub surface with a brush to remove any
debris that could aect the sealing.
3. Locate the rafter center and mark it.
4. Place the tile hook with the hook itself in the valley of the next tile below. Drill one 7/32" pilot hole in
the rafter center, taking care to keep the hook in the valley of the tile below. Backll this hole with a
roof- compatible sealant. For at tiles, try to avoid having the hook land directly under a joint between
tiles, this will create a larger gap or more notching than necessary.
5. Install one 5/16" x 4" lag screw on the row of holes closest to the tile hook arm (image 1). If possible,
install the screw in one of the three holes directly next to the arm. If the lag screw must be installed in
one of the seven holes furthest from the arm (denoted by the red rectangle in image 2), install three
deck screws in the pattern shown by the green circles below.
6. Adjust the height of the tile hook as necessary using the bolt shown in image 3.
7. Flash the surrounding area and lag screw head with roof-compatible sealant as necessary. Refer to Tile
Hook Subashing Installation guide on the next page.
8. Replace the tile that was moved and/or removed, or install the tile replacement ashing.
If it is to be notched, mark the tile for notching. Notching can be done with a grinding wheel or by
using a chisel.
9. Rail can be leveled using the bolt shown in image 4.

TILE HOOK SUB-FLASHING INSTALLATION
TOOLS REQUIRED:
Caulking gun, roong mastic applicator
MATERIALS REQUIRED:
Roong mastic, reinforcing fabric, roof sealant
1. Apply a continuous line of the roong
manufacturer’s approved sealant on the
underside of the ClickFit tile hook sub-
ashing to form a U-shape around the
raised edges.
2. Lower the sub-ashing over the tile
hook base. It may be necessary to move
adjacent tiles to easily lower the sub-
ashing onto the roof deck.
3. Place the sub-ashing over the base of
the tile hook so the ashing covers the
entire base.

TILE HOOK SUB-FLASHING INSTALLATION
1. EcoFasten recommends following the
TRI guidelines three-course sealing
method. Start the three-course sealing
method by applying a layer of roong
mastic over the edges of the tile hook
sub-ashing.
2. Place strips of reinforcing fabric over
mastic to cover approximately 2" from
the edge of the sub-ashing in both
directions. Place strips on the side rst,
then the top edge.
3. Apply a nal layer of mastic to
completely cover the reinforcing fabric.
The ashing is now installed and sealed.

CLICKFIT USING SIMPLEBLOCK-U®
PRE-INSTALLATION:
The SimpleBlock-U can be installed on many dierent standing seam proles. See SimpleBlock-U
Installation Manual for compatible and non-compatible standing seam proles. Be sure that
each standing seam is no thicker than ½" in width.
INSTALLATION:
Position the SimpleBlock assembly on the panel
seam. Make sure the block is fully seated on the
metal seam.
Torque the 2 preinstalled oval point set screws to
150in-lbs using the included 3/16" hex drive.
Included with the block, slide the hex holt into the
channel on top of the SimpleBlock-U assembly.
Place the ClickFit Universal L-Foot over the hex bolt
followed by the serrated ange nut and torque to
150in-lbs.

INSTALLING THE RAIL
1. Place the rail in the Clickers.
2. Ensure the rails extend a minimum of 2”
past the last attachments in each row.
3. Push the rail into the L-foot clicker
starting on the side with the plastic
clips rst, then roll the rail into seated
position. Verify the rail is sitting ush
with both ledges. If attachments
are extremely misaligned it may be
necessary to loosen the leveling bolt
and adjust the height of the L-foot.
Tighten the clamping bolt to 144 in-lbs.
4. Level the rail if necessary by loosening
the bolt attaching the Clicker to the
L-foot or tile hook.

INSTALLING END CLAMPS
AT THE END OF A ROW
1. Install the last mid clamps in the row.
2. Measure the rails from the last mid clamp to the module width plus 1".
3. Cut the rails at this mark. There is some adjustment in the end cap/clamp so it does not
need to be a perfect cut.
4. Install end clamps and end caps, tighten to 96 in-lb
ALTERNATIVE METHOD:
1. Install the last module in the row, tighten the mid clamps.
2. Using a circular saw with a metal blade, or carefully with a reciprocating saw, cut the rail
approximately 1" past the edge of the last module.
3. Install end clamps and end caps, tighten to 96 in-lb
Replace the tile that was moved and/or removed, or install the tile replacement ashing. If it
is to be notched, mark the tile for notching. Notching can be done with a grinding wheel or by
using a chisel.

BONDING PATHS
Bonding paths are carried throughout the array in a variety of ways. They are carried module-to-
module and module-to-rail through mid clamps, carried at rail-to-rail connections through the
splices, and carried row-to-row using module jumpers or grounding lugs with bare copper. For
easy row to row bonding, EcoFasten recommends using our Module jumper.
