Most of the install instructions I've seen for the first aid box call for using self-tapping screws to attach the box bracket to the underside of the seat. The problem with that is that it's almost impossible to find the correct self-tapping screws for this application. Instead of going that route, I decided to tap the holes myself in advance and then use regular bolts to attach the bracket. I chose to use bolts instead of screws because I wanted to use a ratchet instead of a screwdriver as you can get more leverage with a ratchet. I also decided to use washers with the bolts for extra strength.

	1. Locate your tapping tool and your 6mm tapping bit.
	2. Raise the seat as high as it will go. Move the seat as far back as it will go. Tilt the front of the seat as high as it will go. Look under the seat and locate the 3 holes you need to tap.
	3. Tap the holes one at a time. When tapping, make sure you turn the tool backwards 1/4 turn once in a while in order to thread the hole properly.
	3a. Here is what a properly threaded hole should look like.
	4. Locate the bracket.
	5. Locate the bolts and washers.
	5a. Here is a picture of the bag the bolts came in.
	5b. Here is a picture of the bag the washers came in.
	6. Place the washers on the bolts and bolt the bracket to the underside of the seat using the three holes you just tapped. Tighten the bolts securely but do not overtighten.
	6a. If you overtighten a bolt and strip a hole (like I did) you can use a slightly larger bolt to fix this mistake. The original bolt is 6mm x 12mm. This is equivalent to 0.236 inches x 0.472 inches. A 1/4" x 1/2" bolt is just slightly larger and should do the job nicely. You should be able to use the same 6mm washer with this new bolt. Here the 1/4" x 1/2" bolt is on the left, the original 6mm x 12mm bolt is on the right.
	7. Locate the first aid box. Slide the box into place under the bracket.
	7a. Make sure that the box slides all the way onto the bracket. To make sure, check the inside of the box to see if the tab has "clicked" into place.
	7b. Here is a closeup of the tab in place.
	8. Once the box is in place confirm that the seat can still travel through its' entire range of motion without interference. Here the seat is lowered to the floor, you can see that there is still a little room underneath the box and that it is not actually touching the floor.
	9. Once you've confirmed that the box does not interfere with the seat's movement you're done! Back to Top
