Application

Affixing Lap Fastener Nuts to Panels

Lap fastener nuts are to be installed while panels are still on the ground. On one vertical edge of a panel, mark the required lap fastener locations approximately 18-20 inches apart, including one lap fastener close to each purlin. When stacked, several panels requiring the same lap fastener spacing can be marked at the same time. Lift the uppermost panel in the stack and place a lap fastener nut so that it rests on the second panel in the stack with the tabs facing up.

With the lap fastener nut in position, lay the uppermost panel down again. Use a hammer or similar object to lightly tap the uppermost panel from the top until the pointed tabs protrude through the panel from the underside. Bend the tabs over by lightly tapping on them with the hammer. Repeat at each required lap fastener location on each panel.

Fastening Lapped Panels Together

After the panels are positioned on the substructure, overlapping panel edges are fastened together by means of self-tapping screws which are screwed through both panels and into the lap fastener nut, which is attached to the underside of the bottom panel. Whenever panels are fastened directly to the substructure, an additional lap fastener must also be installed close to the purlin or girt.

Note: It is not necessary to apply sealants between overlapping panels. Sealants are not required and will only result in unsightly dirt streaks within a short period.

Light Weight and Affordable Office Decor
Color: Dark Mocha, Size: 3 Panel
I always read reviews before purchasing- so I understood this was going to be a small, light weight tri-fold. It is not meant to be extremely durable- so it wouldn't be great to have around children or animals - but is functional for certain situations. I use this as a divider between my work from home desk and my bed during the day and it is the perfect tool to keep my brain in "work mode", and not sleep mode.

Looks good and is stable
Color: Dark Mocha, Size: 3 Panel
This is perfect for my needs. I have a large bathroom window that anyone can see the toilet when the window is open. The weather is so beautiful here for many months and I hated keeping that window closed. This screen is perfect. It covers the open part of the window so no one can see in but the air flows freely (the glass is frosted so it is not a problem when closed). The screen is very lightweight and came fully assembled (which is amazing anymore). It feels stable and I think it is a good value for the money.

Five Stars. Exactly what I needed for my space
Color: Black
I live in a small NYC apartment, so creating separation without making things feel cramped is always a challenge. This divider did the job perfectly. It was easy to set up right out of the box. No complicated instructions, just unfold and place it where you need it. The size is great. It actually gives real coverage and privacy without looking bulky. The fabric looks clean and professional, and the black color blends well with everything. I’ve used it to separate my workspace from my living area, and it instantly made my place feel more organized. It’s also lightweight enough to move around, but still sturdy enough to stay in place. If you need a simple, affordable way to create privacy or sections in a small space, this is a solid choice.
