Frequently Asked Questions

Why is the PlyFASTner hardware I just purchased different from what I bought last year? It uses a new stainless steel Flush Anchor component in place of the original permanently-installed lags which protruded from the exterior surface when not in use. The new Flush Anchor system uses a removable bolt that serves the same function as the lag. But when the removable bolt is removed, and the plug is inserted, the assembly blends unobtrusively into the exterior surface. The Flush Anchor system still allows plywood panels to be secured quickly, without tools. The original lag-based hardware is still available from the factory.

What size hole do I drill for the Flush Anchor? The Flush Anchor requires a 1/2" diameter hole by 1 1/4" deep, preferably made with a flat spade (paddle) bit.

How do I insert the Flush Anchor component of the PlyFASTner system? The Flush Anchor was designed to be inserted with the same 1/2'' flat spade bit that was used to drill the hole. Keep the bit on axis (straight) so that the point does not scar the internal threads of the Flush Anchor. The removable bolt (a standard 1/4'' x 20 stainless steel bolt) is inserted by hand, finger-tight ONLY.

What is the correct spacing when installing Flush Anchor hardware? According to the SBCCI’s Evaluation Report # 2247, when the panel width is 48" or less, the anchors cannot exceed 30" apart. The spacing from the top or bottom of the panel to the first anchor can not exceed 20". The anchors only need to be placed on two opposite sides. Download instruction sheet for details.

What is the largest panel size that requires only 4 PlyFASTners?
48'' x 70'' (two for each opposite side).

How do I install panels to cover an oversized opening like a sliding glass door? Oversized openings can be protected using two sheets of plywood with the 8' dimension running horizontally. Since the 48'' span is exceeded, the PlyFASTner spacing requirements change to 15" center-to-center and 9’’ to the top or bottom. Anchors are only required on two opposite sides.

How do I install the PlyFASTner system on my brick veneer house?
Brick veneer will not hold the required loads. This installation requires Flush Anchors long enough to be inserted through the brick and threaded into the 2 x 4 framing by 2 1/2''. This hardware may be special ordered from the factory.

How do I install the PlyFASTner system on my masonry block house?
Tested and approved Powers AC 5.5 Plus Epoxy or equivalent must be used in a solid
grout-filled block. The Flush Anchor must be imbedded a minimum of three inches in epoxy
in the solid grout-filled block.

Is the recommended masonry installation considered “vibration resistant’’ as required by code? Yes. But to achieve vibration resistance, the block cell must be filled solid with grout. No Anchor can achieve vibration resistance in a hollow CMU. Powers AC 5.5 Plus Epoxy is the tested and approved adhesive to qualify as vibration resistant by the SBCCI.

I noticed the 3/8" epoxy nozzle will not fit into the 5/16" drilled hole. Since the hole cannot be filled from the surface, how do I fill the drilled hole with epoxy? PlyFASTner provides a clear plastic extension tube with each nozzle purchase. This tube allows the hole to be filled from the bottom and eliminates air pockets.

I was given a box of screws by my builder to fasten storm panels to our vinyl-sided house. Does the PlyFASTner system work with vinyl? PlyFASTner is suitable for all exterior surfaces, including vinyl siding. We at PlyFASTner do not consider screws as a feasible option because resulting damage to the trim would be unacceptable.

My vinyl windows have no trim. Where do I install the anchors?
PlyFASTner Flush Anchors must penetrate through the vinyl siding and be anchored to the structural framing inside the wall. The preparation hole for the Flush Anchor is drilled through the vinyl siding. When fully inserted, the head of the Flush Anchor will protrude 1/4" through the outside of the siding. The removable bolt will need to be longer than the standard 2", since the window extends beyond the siding. After measuring the required length, the removable bolt may be ordered through the factory or purchased locally. Ask for a standard 1/4'' x 20 stainless steel hex head bolt of the measured length.

Which building codes does the PlyFASTner system meet? The SBCCI PST & ESI Evaluation Report #2247 states that the PlyFASTner system was tested in accordance with ASTM E 1886-97 and meets the requirements of the Florida Building Code, the Standard Building Code and the Standard for Hurricane Resistant Residential Construction (SSTD 10-99). The International Building Code is based on SSTD 10-99 and therefore the PlyFASTner system meets all International Codes.

How much force can the PlyFASTner hardware withstand? Code requires any system to hold a minimum of 78 PSF. The PlyFASTner system held in excess of 100 PSF for 10 second duration. This force would apply 533 pounds of force on one PlyFASTner.

What wind speed is 100 PSF equivalent to? 100 PSF is equivalent to a
200 MPH wind.

Will I receive an insurance discount if I install the PlyFASTner system? Some insurance companies do provide a discount if a windborne debris protection system is in place. Since the PlyFASTner system meets code, a discount should be received.

How is the best way to store protective panels? Plywood may be stored vertically (on edge) or horizontal (flat). Since panels can be used year after year, they should be stored in a dry area and not subject to blowing rain or direct sunlight. Panels should not be stored directly on a concrete slab or within 18 inches of soil. But remember, if panels are easily accessible, they will be more likely to be used.

Is there a simple and secure rack which will store panels against a wall? Cut two 2 x 4’s so that the length in inches of each is half the number of stored sheets plus 7''. Then nail a 3” 2 x 4 block flat on each end of the 2 x 4’s. The panels will stack snugly between the blocks (Photo A). Example: for 20 sheets, cut two 17'' 2 x 4’s and four 3'' blocks. This will keep the panels off the slab and stored tightly together. One door hinge mounted securely to the wall slightly above the stack with an upside down ‘’L’’ shaped arm will prevent the stack from falling over and allow for easy removal. (Photo B)
