- In your box you will find a small bag of 4 screws and 4 washers. These are the items you need to use to attach your couplers.
- If you did not purchase couplers from us, no problem. You will need to have four #4 x 5/8 inch screws and four #6 flat washers. These can be found at any hardware or big box store. They are standard items.
YOU MUST remember to use the washers when you install your couplers. Failure to use a washer could cause a dimple on the top of your base plate.
- You need one screw on either side of the coupler box. There is no need to fill all the holes on the coupler box.
- Please DO NOT over tighten the screws on the coupler. There is no need to crank the screw down. Use a gentle touch, stop when secure. If you want to, you can touch up the screws and washers with flat black paint
