This Secondary Lint Trap is popular and we’ve seen it used with multiple motives.  NOTE: It is designed to be installed (recessed) in the cell of a 2x6 wall.  Many of our customers have alternatively installed it outside of the wall with leakage issues.  Please read the section below detailing the modifications necessary to minimize pressurized discharge when not recessing the DryerTrap in the wall cavity. 
This 180-degree lint trap exhibits male and female 4 inch connections connected to the 6x6x5.5” deep body.  Framing stud mounting flanges are on each side.  The cover plate door and integral screen is designed to friction lock against ½” or 5/8” drywall.  The unit is sturdy, well designed and reasonably efficient.  It features one hand operation with the door and screen combined as one solid unit. The door is finished in appliance white (powder coated) with clear inspection window. With a 5-1/2" depth, it can be installed in nominal 6" wood or metal stud walls.  Screen is two layers of metal screen hemmed in a frame. 
Hanging the DryerTrap on the wall or setting the unit on the floor is ok but requires a modification to prevent the pressurized discharge from escaping.  Apply to the inside flat portion of the door circumference a strip of foam style weather-stripping. When closed, the rim will seal against the foam strip minimizing any leakage of air and lint. 
Note: If more than 6 units are desired, either create a second (new) order or contact us prior to completing your order.

Great so far
  So far so good. It went in well - I built 2x6 walls so it fit perfectly. When I first hooked up the dryer and turned it out the exhaust blew the lint screen insert right our of the Dryer Trap Box! I tried to turn the insert 90degrees and the only way it would fit was the way I had it with the knob in the top left corner. I was afraid I would have to tear my wall out and re-seat the box turning it around. There was no "flow" marking on the box itself and no directions to speak of. I taped the insert on 4 sides to get through the laundry of the day. The next day I played with it a bit more and the insert would fit with the knob on the top left corner. The insert did not "blow out" and seems to work good - so far. There is a bit of exhaust smell on the high heat settings but hope once I seal the drywall with my formica backsplash and finish it the smell will go away (I hope!). I did try to contact the company via email with my concern with NO REPLY!

Dryer Trap - Secondary lint trap
  In my previous homes I did not have a basement and did not have the problem of venting the dryer up and out of the basement so I was a little challenged on how to solve this big problem. I was getting lint dust all over, the long exhaust pipe up the basement wall was getting clogged with lint which also accumulated moisture. Big problem! I happened to be out of the country and using a laundry facility at a dorm type building when I noticed that the engineers had installed a locally manufactured secondary lint trap (I came to know that term later after finding the DryerBox website)to service 8 dryers. It was just like the Dryer Trap but industrial sized. I told myself that I would make it myself from scratch. Just before I was heading to the hardware store to buy the materials I happened across the Dryer Box website and ultimately the proverbial answer - the DryerTrap! Long story I know, but I installed it horizontally and took the advice of other postings regarding sealing the box and man oh man does it work like a charm! No more lint all over the basement, no more clogged exhaust pipe. My wife loves it, I love it, the dog loves it!! Thanks DryerBox!

A Quality Item
  The Secondary Lint trap is a well made item. I installed it in horizontal orientation with access to clear the filter from an adjacent closet wall recess. I added a foam gasket and 2 threaded studs with wing nuts to the access door to ensure no air leakage. I also sealed all the seams of the unit with foil tape. What can I say? Belt and Suspenders for me! " I can hardly wait to put my new dryer to work and empty my secondary lint filter for the first time. Can you tell that I don't get out much? :-)

A Must Have
  My house has a second floor laundry room and when it was built the dryer vent was built to blow out the front of the house. This caused all the lint to blow out and stick to the front of the house, top of the roof and left an ugly, horrible mess for everyone to see. My handyman found the DryerTrap online for me, took less than 1 hr to install it and it works beautifully. No more lint. I LOVED IT!!

Very good product
  Have used this item for the past few weeks. It is in a basement, so not installed in a wall. To mount it, I put 2 screws through the back into a 2x4. As suggested by others, I put weather strip around the cover to seal it ( should come this way). I also use large rubber bands to keep the seal tight. It works great. With the minor modifications above, it is perfect and protecting my vent fan.

Great product
  I agree this is a great product. I installed dryer venting in an old home and my best option was to run the vent using a very long run to a basement window that has a window well. I didn't want lint building up in the window well, didn't want to pay for cleaning the ducts often because with the long run it would get expensive, and didn't want lint build-up in the pipes. I installed this right behind my dryer, between the Dryer Flex and the rigid pipe. I empty it every few dryer runs. The fit was loose so I tried weatherstripping as someone else had recommended, but couldn't get a tight fit. Instead I use 2 rubber bands to hold the cover on tight, and that works perfectly. Between this and using 2 dryer-ells for the angles, I feel like I have a pretty efficient system even though the vent is very long. Thanks for your creativity! I can't believe everyone doesn't have a secondary lint filter to prevent build-up in pipes.

Pretty good
  I did install the trap. The fittings are good but there should be a "female" on the bottom since the duct work goes up. Also the door itself should have some insulation around the edges to stop the heat and some lint from blowing out. I did install some weather stripping around the door edge inside the flange and it is tight and works really well.

lint trap
  Installed the lint trap at my Parents house. Was having to clime on the roof every year to clean out the lent buildup at the exhaust. My mom loves it, has to clean it out every other load. I see so many reviews that install it out side the wall I wish they would build one for that use or a outer housing to install it in. But still a A+ product.
