Step 3– Connect Risers.
Drill upright risers right into your frame. The dimension depends on you, though even more 2x4s will work penalty. Additionally, the distance between them is your choice, though you’ll require at least 1/8 of an inch to make up swelling of the wood– anything much less and also the swelling could damage your risers. Many wood driveway entrances do not have more than an inch of room between risers.
