Common Questions
What is this shim used for?
It's a 1/4" rubber underlay placed beneath a hitting mat or strip so its height matches the surrounding turf, avoiding a lip or trip hazard.
Which size should I order?
The 12" x 30" option is sized for under a hitting strip. Longer lengths (16–50 ft) are for leveling wider runs across your bay floor.
Does it need adhesive?
No, it's designed as a simple drop-in underlay.
Can I combine sizes to cover a longer run?
Yes, the 12" x 60" two-piece option and longer lengths can be combined to match your total floor run.
