The Problem: Most of us have car trunks filled with loose boxes. When we drive around, these boxes slide around, or worse, tilt over spilling out all of our precious worldly possessions. Some of us have trunk nets. However, these trunk nets are better for loose small items (not boxes or large cargo). One could also buy giant plastic bins with grippy feet. These work, but you will have to shell out $20 or more for a 1 size bin. What if you went shopping and just bought an item that was larger than the bin. what if the product box couldn't fit into your trunk because your trunk bin took up too much space? What if you had boxes of different sizes? Dont you wish you had a method of holding the boxes, packages or cargo in place regardless of its box size?

The Solution: Create a set of cheap, small, strong and most importantly configurable cargo blocks. These blocks will fit any box size and can be easily stored in nook in your trunk when not in use. Essentially, my blocks will simply stick to the floor of the trunk in multiple locations holding boxes and cargo in place.

Estimated cost: $5-6 for set of 4
Estimated build time: <5 mins

Materials

  • Joist Angle or Aluminum Angle, 1 to 1.25 inch wide ($.50 usd to $.90 usd ea)
  • 1 inch wide self adhesive velcro tape or strips, ($2-$4 usd for 12-18in)

Tools

  • scissors
  • sand paper (optional)
  • marker (optional)

Step 1: Prepare the Angle

Picture of Prepare the Angle

Remove all labels or stickers from the angle. Clean the angle with a moist towel to get rid of any debris or sticky glue from the label. This will help the velcro adhere to the angle. The joist angle I am using is sized: 1-1/2" x 1-1/2" x 1-1/4".

If you bought an aluminum angle that needs to be cut, then measure out the length you want your block to be and cut accordingly. Please wear goggles.

Optional: sand down the edges of the angle.

Just made a set of these for my brother, who always complains about everything rolling around in his trunk. They work like a charm - thanks for posting!

Smart idea.

Nice one.

I made something similar to this years ago, using the old style library metal book ends, lightweight, smooth edges, about 8 inches tall and a large enough base for lots of Velcro. Worked for a while until the cold weather hit and even the Industrial Velcro let go inside the cold trunk of the car.

Easy for anyone to do. Effective for use. Inexpensive for what they do.

Full on WIN!

Home Depot in the US now sells Velcro Extreme. This is the stuff I used to use for industrial work - formerly only available wholesale. REAL adhesive that won't come off. AGGRESSIVE velcro stickum.

re: sharp edges, can always take a grinder (large or small) and round of the corners and edges, sure a bit more work. But you could also get some plasti dip and dip the up end in it and then brush more plasti dip on the bottom section. could wrap the velcro around the bottom section as well to cover the edges/corners.

nice idea

My new car came equipped with lots of much larger cargo blocks; they're all about 6 inches tall, so they really hold. Steel angle iron has sharp corners that would puncture boxes and certainly plastic shopping bags. I wouldn't lay new clothing or groceries near steel or aluminum blocks for fear of tears. Why not use some lumber or plastic things instead, which can have rounded corners? Women would appreciate the softer side of those things, I guarantee.

That is something I wish I had thought of. Will have to add to my to-do list.

Brilliant

Outstanding idea! thanks

So simple yet so ingenious. I will be using this a lot...

BoskyO2 months ago

Great idea. You could also use Simpson angle brackets, available at the big-box & other hardware stores. They may cost a bit more, but they also come in larger sizes for more grip & tip control, if it is needed.

bakunin2 months ago

This is ingenious! I love it.

May I suggest you include a picture of the finished setup in your Introduction step?

Denger2 months ago

Great idea for a simple, easy solution. I have found that for transporting irregularly shaped items (plastic grocery bags, for example) unrolling some Duck brand EasyLiner (available from Amazon and elsewhere) or equivalent is wonderful for preventing loads from slipping around. Now to prevent tip-over, that's another matter...

Excellent Idea. Thanks.

I normally hate velcro. . . . but now that I know there is extreme velcro I may come back.

Thanks for the info and the cool use!

mcollazo2 months ago

Awesome idea! Going to make a set this weekend. By the way @Killbox, he did do what you said on the right side of the box (you have to look closely). I'mm going to try it both ways to see what works better for me.

mantissa2 months ago

Can I just ask; what type of velcro is that? It looks unlike any other velcro I have seen (for sale in the UK!)

jheiss mantissa2 months ago

It looks like the stuff that is sold in the US as "Velcro Extreme" Available via Amazon.

Poppy Ann2 months ago

A great simple idea i will be making some very soon.

FOfilms2 months ago

will eventually make a mess of your carpet, the HD velcro bites hard and doesn't want to let go

agulesin FOfilms2 months ago

How about putting some strips of the same Velcro on the carpet at strategic spacing, then only fix the corners to those strips...

LynxSys2 months ago

Great idea! You might consider coating the upper portion of the bracket in Plasti-Dip (or just wrapping them in duct or gaffer's tape) to give them some grip and protect your belongings from the edges of the metal.

Now I just have to figure out how to adapt this idea to a trunk with a plastic liner in it...

I carry lots of tools for work and I tried to just put velcro on the carpet of the trunk. Problem was now the trunk carpet rolls around lol. Is your carpet attached to the trunk somehow?
imjasonc (author)  mrandle2 months ago

my carpet in the trunk is part of the floor board. ive had cars where the carpet just laid on top of the floor board in the trunk, but i never experienced rolling. maybe you can put some velcro between the carpet and the floor of the trunk. that way you can still move the carpet if needed.

mrandle imjasonc2 months ago
Tried that but then the Velcro just pulled off the backing of the carpet. Maybe I can spray glue the carpet to the spare tire cover.
clazman mrandle2 months ago

Is the back of the carpet un-coated? That is a problem. What if you applied a rubber type coating to the back side of the carpet, working it into the fibers? That would create a better surface to apply the self sticking velcro.

thancock42 months ago

one of the BEST ideas i have seen for YEARS. Simple, elegant and super cheap. These would walk off the shelf at autoparts stores!

palletmike2 months ago
Built a couple of sets of these as my wife and I both needed something. They work great for us both! Voted and appreciate this idea very much.
killbox2 months ago

if you flip them around so the box is on the bracket, it would likely anchor even better since the weight of the box will keep it attached rather than just relying on velcro's force (like how many book ends use the weight of the books. )

I think it would need a sort of counter-balance on the bottom like bookends have. If it was an inverted T shape it should help with the stability.

imjasonc (author)  killbox2 months ago

interesting idea! enough for me to run outside to my car to try it.

sadly that did not work. unlike a bookend, boxes in cars need to deal with g forces from movement. if you push the books with a bookend, the books and the bookend will still move. the idea of the weight of the books as an anchor only works if the books and the shelf are stationary. im sure if you shook the bookself, even if the bookend, the books will still shift.

I like the idea of turning them around. How about using more of them to compensate?
