REV DATE: 07/16/2020VERSION: 2.0
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”.
3.1 Attaching to the Roof
The attachments are fastened to the rafters. Attachments are height-adjustable to level
the system on uneven roof surfaces.
3.2 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.
3.3 Attaching the modules
The modules are attached to the rails by means of mid clamps and end clamps.
Installer must review the module manufacturer’s installation manual to conrm
compliance to the warranty terms and conditions.

• 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 (l/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.*
INSTALLING CLICKFIT

REV DATE: 07/16/2020VERSION: 2.0
Installation of flashing and L feet
• ClickFit for comp shingle roofs uses EcoFasten Solar’s GFl watertight ashing system
• Other roof types may use dierent EcoFasten Solar attachments, see www.EcoFastenSolar.com for more
information.
Installation Steps:
1. Locate rafter lines from section 5.2.
2. Drill l/4” 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. Ensure the ashing is pushed to the third-course of shingle to prevent water
inltration through the vertical joints between shingles.
4. Align GFl 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 a ring of EPDM is visible around the circumference of
the bonded washer.
Tighten the lag 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 two
Clicker “arms” should be facing downslope*
FLASHING AND L FEET

REV DATE: 07/16/2020VERSION: 2.0
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 l/4” 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. 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 below), 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 the fourth image.
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.

REV DATE: 07/16/2020VERSION: 2.0
CLICKFIT TILE HOOK SUB-FLASHING INSTALLATION STEPS:
Tools Required: Caulking gun, roong mastic applicator
Materials Required: Roong mastic, reinforcing fabric, roof sealant
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.
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.
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.
Place the sub-ashing over the base of the tile hook so
the ashing covers the entire base.
Apply a nal layer of mastic to completely cover
the reinforcing fabric. The ashing is now installed
and sealed.
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.

1. Place the rail in the Clickers.
2. Ensure the rails extend a minimum of 2” past the last attachments in each row and that each rail is
aligned with the next row North and/or South.
3. Roll the rail into each Clicker, an audible “click” should be heard. If attachments are extremely misaligned
it may be necessary to loosen the leveling bolt, snap the Clicker onto the rail, then re-tighten the leveling
bolt to 142 in-lbs.
4. Level the rail if necessary by loosening the bolt attaching the Clicker to the L foot or tile hook.
*Ensure the tab on the Clicker is aligned with the rail edge as shown below*
INSTALLING THE RAIL

6.7 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 l”.
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
l” past the edge of the last module.
3. Install end clamps and end caps, tighten to 96 in-lb
