While this homeowner chose to remove (4) of the standard (8) rods in our 36” Residential posts configurations, we encourage you to check with your local building codes before doing so. However, the homeowner sought our guidance on whether they could remove the empty barrels inside the posts? No, you cannot. However, there are non-slotted, solid barrels available for purchase should you choose to replace the standard slotted barrels for a cleaner look.
