3. Installation (Setup)
The PROFLO PF5331 Double Stud Shoe is designed for straightforward installation to reinforce studs where pipes or conduits pass through.
Required Tools (Not Included):
- Drill
- Appropriate fasteners (screws or nails suitable for wood studs)
- Measuring tape
- Pencil
Installation Steps:
- Prepare the Stud: Identify the location in the non-load bearing wall stud where the pipe or conduit will pass. Drill a hole of appropriate size through the stud.
- Position the Stud Shoe: Place the PROFLO PF5331 stud shoe over the drilled hole, ensuring the pipe(s) or conduit(s) will pass through the channels of the shoe. The shoe should straddle the weakened section of the stud.
- Secure the Stud Shoe: Using appropriate fasteners, secure the stud shoe to the wooden stud through the pre-drilled holes on the flanges of the shoe. Ensure the shoe is firmly attached and does not move.
- Run Pipes/Conduits: Once the stud shoe is securely installed, run your plumbing pipes or electrical conduits through the protected channels.

4. Function and Purpose
The PROFLO PF5331 Double Stud Shoe serves as a passive protective device. Once installed, its primary function is to:
- Protect Pipes/Conduits: It shields pipes and electrical conduits from accidental penetration by nails, screws, or other fasteners during subsequent construction or renovation activities.
- Reinforce Studs: It reinforces the structural integrity of a wooden stud that has been weakened by drilling holes for utility lines, particularly in non-load bearing applications.
No active operation is required after proper installation. The stud shoe performs its protective function continuously.
5. Maintenance
The PROFLO PF5331 Double Stud Shoe requires minimal maintenance due to its durable construction.
- Periodic Inspection: If accessible, periodically inspect the stud shoe for any signs of damage, corrosion, or loosening of fasteners.
- Cleaning: If necessary, clean with a damp cloth to remove dust or debris. Avoid abrasive cleaners.
- Damage: If the stud shoe appears damaged or compromised, it should be replaced to ensure continued protection.
6. Troubleshooting
Most issues related to a stud shoe are installation-related or due to improper application.
- Stud Shoe is Loose: Ensure fasteners are properly tightened. If the stud material is compromised, consider using larger fasteners or relocating the stud shoe if possible.
- Pipe/Conduit Not Fitting: Verify that the drilled hole in the stud and the channels of the stud shoe are appropriately sized for the pipe or conduit being used. Do not force pipes/conduits into channels that are too small.
- Damage to Stud Shoe: If the stud shoe is bent, cracked, or otherwise damaged, it may not provide adequate protection. Replace any damaged stud shoes immediately.
- Used in Load-Bearing Wall: If the stud shoe has been incorrectly installed in a load-bearing wall, consult a structural engineer or qualified professional to assess and rectify the situation. This is a critical safety concern.
