Klein Tools 54817MB – Frequently Asked Questions

1) Will the Klein Tools 54817MB cup holder mount to any MODbox rail, or only certain boxes?
It attaches to any MODbox system side rail. The one-handed release lets you clip it on and slide it to a different spot on the rail without tools or a second hand. It is built for MODbox rail system components specifically, so it will not clip to a non-MODbox box or a generic tool cart rail.
2) Does the cup holder keep a drink upright when you roll the MODbox stack around?
That is the point of the swivel. The holder pivots so the cup stays level while the MODbox system is tilted and in motion, which is the difference between this and a fixed bracket. Flexible fingers inside grip the container so it does not rattle loose while the stack is being wheeled.
3) Do I have to leave the cup holder on the outside of the box when I pack up?
No. Pull it off the side rail and it stores inside the Rolling Toolbox or Medium Toolbox when those are fitted with the Internal Rail Accessory. The internal rail is a separate item, so if you want it stowed inside rather than riding on the outside, order that too.
4) What size drink containers fit the MODbox cup holder?
Rather than a single fixed diameter, the holder uses flexible fingers that flex to grip different container sizes, so a travel mug, a bottle, or a standard cup all seat. The opening sits within an overall footprint of 6.2 in wide, 4.2 in long and 7.6 in high, so it is sized for normal jobsite drinkware, not an oversized cooler jug.
5) How much rail space does the Klein 54817MB take up, and will it hang past the side of the box?
Plan on about 6.2 inches of width and roughly 4.2 inches of projection off the rail, with 7.6 inches of height. At 0.54 lbs it adds almost nothing to the load, but the 4.2 inch stick-out matters if you are squeezing the MODbox stack through a doorway or into a van shelf, so mount it on the side with clearance.
6) What part number do I order for the Klein MODbox cup holder rail attachment?
Klein Tools 54817MB is the cup holder rail attachment. It is a single model with no finish or size options, so that one number covers it.
7) What is the Klein MODbox cup holder made of, and will it hold up on a jobsite?
Hard plastic throughout, in orange and dark grey. There is no metal in it and no fabric to soak up spills, so it wipes down and it will not rust in a service van. It is a beverage holder, not a load-bearing accessory.
8) Can I run more than one MODbox rail attachment at the same time?
Yes. The cup holder is one of the MODbox rail attachments and it interconnects with the rest of the system, so you can populate the side rails with several accessories and move each one along the rail with its own release. Position them where the 4.2 inch projection off the rail will not foul the next attachment.
