Nifty Catch-All Xtreme floor mats installed. If you're looking to replace your floor mats or if you want something that'll retain a reasonable amount of mud and water, these are worth considering.
What's in the boxes:
The slotted end of these fasteners pops into the holes (from the bottom) on the mats. Each mat has two holes. Once everything is positioned, the threaded end is turned into the carpet.
At first glance it didn't look like the mats fit too well but after a little experimenting they fit perfectly. I used a small L-shaped tool to lift the trim and slid the edge under. Flat screwdriver sets the fasteners in the carpet. The manufacturer claims that if the plastic screws are removed the holes made by the screws will close. I believe them. Once the screws are set, to remove the mats you pop them off the slotted end of the fastener. The fasteners remain in the carpet until you back them out.
Water check. One pint of water easily contained. You can see the caps on the fasteners are installed here. The area around the fasteners is raised and that's a good thing -- the fasteners and holes they go through are not watertight.
Bad lighting on this pic but you can see how high the mat reaches on the center console.
Back seat mat fits great, too.
Overall and for the time being, the mats seem like a good investment. Expect to pay around $160 for a set unless Trail Duty decides to carry them and offer their usual killer pricing.
One thing these mats aren't good for: If you want a rigid mat that allows you to remove them to dump water, these won't do that. They're rugged but they are very flexible. You'll want to mop-up water before removing them for cleaning.
