Measuring and Marking the Hanger Locations
Before you can install the hangers, you need to determine where they will be placed on the retaining wall blocks. This is a critical step, as the hangers need to be positioned properly in order to support the weight of the shelves or other objects you will be hanging.
To begin, measure the width of the shelf or object you will be hanging. This measurement will determine the spacing between the hangers.
Once you know the spacing between the hangers, mark the locations of the hangers on the retaining wall blocks. Use a pencil or chalk to make light marks on the blocks.
Calculating the Hanger Spacing
To calculate the optimal spacing between the hangers, you need to consider the following factors:
- The weight of the shelf or object you will be hanging
- The strength of the hangers you are using
- The distance between the retaining wall blocks
As a general rule of thumb, the spacing between the hangers should be no greater than 24 inches. However, if you are hanging a heavy object, you may need to reduce the spacing to 16 inches or even 12 inches.
To determine the exact spacing between the hangers, consult the manufacturer’s instructions for the hangers you are using.
| Weight of Object | Hanger Spacing |
|---|---|
| 0-50 lbs | 24 inches |
| 50-100 lbs | 16 inches |
| 100+ lbs | 12 inches |
Drilling Pilot Holes in the Blocks
Before installing the hangers, it is crucial to drill pilot holes into the retaining wall blocks. This step ensures the hangers are securely fastened without damaging the blocks. Here’s a detailed guide to drilling pilot holes:
1. Determine Drill Bit Size
Choose a drill bit slightly smaller than the diameter of the hanger bolts. This will allow the bolts to fit snugly into the holes.
2. Mark Hole Locations
Position the hanger onto the retaining wall block and mark the locations where the holes will be drilled. Ensure the hanger is level and spaced evenly for optimal load distribution.
3. Align the Drill
Use a drill with a level to ensure the drill bit is perpendicular to the block’s surface. This will prevent the holes from being angled or crooked.
4. Drill the Holes
Slowly and carefully drill the pilot holes to the desired depth. The depth should be slightly deeper than the length of the hanger bolts. Use caution not to drill too deeply or damage the block.
For your convenience, here’s a table summarizing the pilot hole drilling process:
| Step | Description |
|---|---|
| 1 | Determine drill bit size |
| 2 | Mark hole locations |
| 3 | Align the drill |
| 4 | Drill the holes |
Inserting the Hangers
Begin by inserting the hangers’ bent ends into the top course of retaining wall blocks, centering them on the grooved faces.
**Tip:** Use a rubber mallet or a hammer with a rubber head to gently tap the hangers into place.
Once the bent ends are seated in the grooves, bend the flat ends of the hangers downward against the back side of the block. Ensure the flat ends are flush against the block’s surface.
Secure the hangers using the provided bolts or screws. Insert them through the pre-drilled holes in the flat ends of the hangers and tighten them snugly using a wrench or screwdriver.
**Tip:** Use galvanized bolts or screws to prevent rust and ensure durability.
To ensure the hangers are installed level, use a level to check the flat ends against the back of the block. If necessary, adjust the bolts or screws to level the hangers.
| Tip: | Use a chalk line to mark a level line on the back of the block before inserting the hangers. This will help ensure they are installed level. |
|---|---|
| Caution: | Do not overtighten the bolts or screws, as this can strip or damage the hangers. |
Tightening the Bolts
