In terms of architecture, corbels are the supporting weight underneath the buildings. Before starting, you must be familiar with the corbels. How they work, and how to install corbels under granite? And where else can it be used except granite? In other words, corbels are support brackets that install underneath the heavy architecture to support their weight. At this point, people are confused about brackets and corbels. The frame gives only support to weights, but corbels provide versatility, value, and different designs according to place. In other words, both have the same functions. Like corbels, brackets also come in a variety of designs.
To acknowledge with corbels, you must be familiar with down terms:

How to Install Corbels under Granite
Step 1: Measurement
- First of all, measure the length from the edge of the cabinet to the countertop’s edge.
- If there is any lip, then measure inside the lip.
- The point must be wide enough to span under the countertop.
- Measure the length of the corbels; each of 36″ support is needed.
- Measure the length of the support required.
Step 2: Cutting
- Cut a ¾ inch of hardwood.
- Measure the width from both ways.
- If you measure 10 inches, then measure 9 inches of plywood by 9 inches.
- If your countertop is square, then take square corbels. The shape of the corbel depends on the countertop shape.
- Use table saw for square measurement of countertop and corbels.
- Now next step is to select material hardwood or plywood? Which one do you prefer?
Plywood: Plywood is the first choice of cabinet-makers.
- Good quality plywood is long-lasting for more than 150 years.
- Plywood holds up the edges for a more extended period.
- Some cabinet makers also choose hardwood for corbels.
- Hardwood panels can be used to cut corbels.
- Hardwood looks better than plywood.
- If it’s not appropriately drilled, it can split.
- It costs significantly more.
- Now it’s on you which one you prefer for your corbels countertop.
Step 3: Draw, cut, and finish
- Now draw a curve onto the square piece of plywood/hardwood from corner to corner.
- You can make any curve; I will prefer a French curve.
- Use a band saw to cut the curve.
- Then use grit paper for sanding it correctly. You can use a 100-grit paper for sanding; it will help the primer stick on the corbel wood.
- When making a French curve, it is not necessary to make it perfect as its curve will adjust the points.
- After sanding, you can finish the corbels for efficiency.
Step 4: Drill
- Place the curve under the counter.
- Please place it in a position that the French curve is facing outward.
- Now the square edge of the French curve should be on the opposite side of the cabinet.
- One square edge must be flush with the end of the countertop.
- Now place the plywood corbel where you want to support.
- Mark off the spacing between each corbel.
- Now place a tri square to make sure the wood corbel is vertical.
- Trace around the corbel to flush against the back of the cabinet.
- Now remove the corbel.
- As you see the marked point, Drill three holes around the tracing. The holes will penetrate through the cabinets, where you have to screw it off inside the cabinets.
Step 5: Installation
- In this step, place a pocket hole jig on the corbel.
- Drill three holes upward from the corbel.
- Ask somebody to hold the corbel accurately from the front and put a screw.
- Now go on the front side of the cabinets.
- Remove any obstacles from the cabinets.
- Now put screws in the corbels to fix it and tell your assistant to tighten it from the other side of the cabinets.
- You can pre-drill holes if you are not satisfied with your driller.
- By following the whole procedure, you can install it on other sides under the granite countertop.
Step 6: Finish the job
- Screw on all the corbels from the inside of the cabinet.
- Using pocket holes and screws to finish the screwing from the top of the corbel to the cabinets down to support it.
- Granite countertops should have pre-drilled holes on the underside of the countertops for mounting purposes.
- Attach the brackets for the countertop with screws and a screwdriver.
- Now put epoxy glue on the shelf and attach a granite countertop to the shelf. Epoxy glue provides bonding support as the support stone offers.
