While cable tray support brackets are typically designed for specific sizes, there are certain situations where adjustments may be necessary. Here are a few instances where size adjustments might be required:
- Misalignment or uneven installation: Sometimes, during the installation process, the cable tray may not align perfectly with the support brackets due to varying dimensions or mounting difficulties. In such cases, adjusting the bracket size can help achieve better alignment and ensure proper support.
- System upgrades or modifications: Over time, cable tray systems may undergo changes, such as the addition of new cables, equipment upgrades, or system expansions. These modifications can lead to varying widths of the cable trays. In such scenarios, readjusting the size of the support bracket becomes necessary to accommodate the changed dimensions.
Methods to Adjust Cable Tray Support Bracket Sizes:
While the adjustments required may vary depending on the specific situation, there are a few general methods that can be employed to modify the size of a cable tray support bracket:
- Slotted Holes: Some cable tray support brackets come with slotted holes. These slots allow for adjustment and flexibility in mounting. By loosening the screws holding the bracket in place, you can slide it along the slots to achieve the desired width. After positioning the bracket, tighten the screws to secure it.
- Adjustable Mounting Hardware: There are adjustable brackets available in the market that can be expanded or contracted to accommodate different cable tray sizes. These brackets often feature a telescoping design, allowing for adjustment in length or width according to the tray’s requirements. These adjustable options can be convenient when uncertain about precise measurements or dealing with varying cable tray sizes.
- Swivel or Rotating Brackets: Some cable tray support brackets are designed with swivel or rotating mechanisms. These brackets allow for rotation or pivoting, enabling the adjustment of the bracket size even after it has been installed. By unlocking the swivel mechanism and rotating the bracket, you can alter its size to fit the cable tray more accurately. Once in position, lock the swivel mechanism to secure the bracket.
While cable tray support brackets are manufactured and sold in standardized sizes, there are methods available to adjust their size to accommodate various cable tray dimensions. Using slotted holes, adjustable mounting hardware, or swivel brackets can provide the flexibility needed to ensure proper alignment and support. However, it is crucial to exercise caution and refer to the manufacturer’s instructions to avoid compromising the load capacity or safety of the cable tray system. Always prioritize the correct sizing and installation of the support brackets to maintain the stability and integrity of the cable tray system.
