Polypropylene Stud Bushing 100 Pack - Protects Wire Insulation

In this review of the OHLECTRIC 100 Pack polypropylene stud bushings, the bottom line is clear: this kit is for electricians, contractors, and DIYers who need a simple, durable way to protect cable insulation where wires pass through metal studs. The main reason to buy is the material and fit - molded, non-conductive polypropylene provides a smooth, rust-free surface that prevents abrasion and makes pulling multiple cables through a single 2x4 in opening noticeably easier. Installation requires no special tools, so the product performs exactly as intended for routine commercial and residential wiring.

Key Features

• High-strength polypropylene: The molded, non-conductive material protects conductors from sharp metal edges and resists rust and corrosion over time.
• Smooth wire pulling: The bushings create a low-friction surface so multiple cables can be fed through the same opening without snagging.
• Tool-free installation: Snap-in design fits into 2x4 in holes quickly and does not require skilled labor or special tools to install.
• Universal 2x4 size: The standard 2x4 in stud bushing with approximately 1.30 in hole diameter suits common construction openings and metal stud shapes.
• Lightweight and flexible: The polypropylene body adapts to irregular stud edges and stays comfortable to snap in during repeated installations.
• Long-lasting protection: Being rust-free and abrasion-resistant, these bushings are intended to outlast iron alternatives in humid or outdoor-adjacent environments.

Who It's For

This 100 pack is aimed at professional electricians, electrical contractors, and facilities maintenance teams who regularly route multiple cables through metal studs and need a reliable, economical protector that speeds up installation. It is also useful for experienced DIY homeowners tackling rewiring or new construction projects who want safer cable runs without custom grommets.

Those who should look elsewhere include projects requiring insulated-rated conduit or specialized firestop-rated bushings; this product is a protective snap-in stud bushing and does not replace conduit, firestopping systems, or other rated barriers where code requires them.

Pros & Cons

Pros

• Non-conductive polypropylene reduces risk of abrasion and prevents rust problems seen with metal bushes.
• Snap-in, no-tool installation speeds work and is approachable for less experienced installers.
• Standard 2x4 in sizing and about 1.30 in internal hole diameter fit common applications and allow multiple cables.
• Lightweight and slightly flexible to accommodate irregular stud edges.

Cons

• Not a substitute for conduit or firestop-rated products when building codes require them.
• Hole diameter and 2x4 in format are standard but may not suit nonstandard stud systems without verifying fit.

Our Verdict

The OHLECTRIC 100 Pack polypropylene stud bushings are a practical, cost-effective choice for routine cable protection through metal studs. They are particularly good value for installers who need reliable, rust-free protection and faster installations without tools. Buy this pack when you need standard 2x4 in snap-in grommets to reduce abrasion and ease cable pulls; choose rated conduit or firestop solutions for code-critical barriers.
