Find a car seat that keeps up with how fast your kids grow with the Britax Highpoint Backless Belt-Positioning Booster Seat. With a higher weight and height capacity than most other brands, this booster car seat helps your child ride safely in a booster longer. This high back booster seat easily converts to a belt-positioning backless booster car seat when your child is ready. Mindfully made from top to bottom, this forward facing car seat is slim and lightweight so it's easy to move from one car to another and fits three across in most vehicles. The protective seat shell, foam-lined headrest, and side cushions help absorb impact energy and are designed to help keep your child's head, neck, and body safe. Plus, the 10-position headrest is quick and easy to adjust with one hand as your little one grows. SecureGuard clip and color-coded seat belt guides make it easy to position the seat belt perfectly and make it easy for big kids to learn how to buckle themselves in safely. Don’t stress about the juice box spills! The removable SafeWash car seat cover is safe to machine wash and dry so you don't have to spend time handwashing it or waiting for it to air dry to keep it looking like new, mile after mile. Premium fabrics and foam offer superior comfort and the two dishwasher-safe drink holders keep your little one's drinks and snacks within reach.

Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.

Solid choice for fuse holder
Size: 300A Fuse Holder
It’s awesome, solid connections for running 0 gauge wire. No issues after using for months! Might upgrade to using 0 gauge wire ferrules to use with this but for now everything is working well.
