Basically you want the size of the hole to allow the iron baluster to fit into it snugly.
Mount balusters without drilling into wood floors.
Drill 1 4 inch to 1 2 inch into the tread floor.
Slide the baluster into the top handrail first and then drop it down into the hole in the floor tread.
This requires drilling a round hole and using a shoe to hide the left over gaps.
The end of the baluster is rounded into a dowel.
Square baluster installation tips.
Not so tight that it has to be beaten down on top of it but not loose either.
Be careful not to over tighten your connector.
Wood balusters may be attached to the handrail and floor in a number of ways.
Metal balusters that are 1 2 inch square will require that you drill at least a 3 4 hole in the floor and handrail surface.
The hole must also be deep enough to allow the baluster to slide up into it high enough to clear the tread cap or landing shoe before it is straightened out and dropped into the 5 8 hole.
First slide your baluster shoe onto the baluster.
Typically if your baluster extends into the upper hole 1 and the lower hole the depth of the upper hole is 1 2 deep.
Measure and cut your balusters 3 4 longer than the distance from the bottom of the handrail to the top of the base tread floor.
Others are installed into a hole in the handrail and may have a wood dowel in the base which goes into the tread or floor.
Insert the included installation screw into the connector and using a drill attach the connector centered on the marked locations.
Round hole with base shoe by far the fastest and easiest method.
If the bottom portion of the wood baluster does not want to come up try rotating it counter.
Some balusters are simply toe nailed into place.
This makes iron baluster installation clean easy and most importantly secure.
We purposely drilled out a deeper hole in top to give us this extra room.
Remember to begin drilling vertically into the railing but once the screw connects with the wood adjust your drill to finish at the correct angle.
Hi so we did have to drill into the drywall.
If you are installing the metal balusters in the same location as the old wood balusters you need to check the size and depth of the existing holes.
This kit works great for banisters but as far as i know there is nothing that will allow you to avoid drilling into a wall other than attaching a piece of wood to it but then you would have to drill the wood somehow or using a pressure mount gate.
Use your best judgement as you should know the material you are installing into step 5 cutting iron balusters to size.
Make sure everything lines up and the pattern is correct before adding glue.
