Super Anchor 1017C Adjustable Floor Joist Safety Bar – Multi-Spacing Fall Protection
The Super Anchor 1017C 4x2 Adjustable Floor Joist Safety Bar offers a versatile, secure fall-protection solution that accommodates varying floor joist layouts. Engineered to fit 12", 16", and 24" O.C. spacing, this single bar provides a total span of 48 inches across three structural members. By locking firmly into place with stainless steel detent pins, the 1017C creates a high-strength anchorage that supports up to two workers using energy-absorbing lanyards or self-retracting lifelines (SRLs). For crews working strictly on fixed 24" O.C. layouts, the Super Anchor 1017A Safety Bar is also available.

Designed for Flexible Safety in Open Framing Operations
The 1017C Adjustable Safety Bar builds on proven design principles, offering enhanced flexibility for modern job sites with mixed structural spacing. Whether your project utilizes 12", 16", or 24" O.C. floor joists, this safety bar adjusts to fit, ensuring the impact load is distributed evenly across three joists. This 3-point distribution provides a significantly more stable and secure attachment point than traditional single-attachment anchors. Its rugged mild-steel construction and Safety Green powder coating ensure it remains a dependable tool for framing crews working in all weather conditions.
Rapid Installation with Precision Adjustability
The Super Anchor 1017C is designed for fast deployment without sacrificing structural accuracy. Featuring patented adjustable legs and quick-release detent pins, the setup is intuitive and fast. The bar includes an integrated 3/16" "bump bar," allowing framers to use a hammer to nudge joists into perfect alignment before locking the bar into place. This dual-purpose tool facilitates quick installation while ensuring that joists are correctly spaced and securely anchored during the critical window before decking is installed.

Super Anchor 1017C Adjustable Safety Bar FAQ
1. How does the 1017C adjust between different spacings?
The 1017C features multiple pre-drilled pin locations along the main bar. To adjust the spacing, you simply move the patented legs to the desired width (12", 16", or 24") and secure them with the stainless steel detent pins. This allows one tool to serve every floor framing project in your portfolio.
2. Can I tie off two workers even if the bar is at its 12" setting?
Yes. The 5,000-pound breaking strength and 2-worker rating apply across all adjustable settings. As long as the bar is correctly spanning three joists and the pins are fully locked, it provides the required safety for two users, each up to 310 lbs.
3. Is this bar compatible with standard 2x4 roof trusses?
The 1017C is designed for the 4-inch wide top chord of an engineered 4x2 floor joist. For 2x4 roof trusses, we recommend the Super Anchor 1010 Safety Bar to ensure the leg geometry provides the most secure grip on the narrower lumber.
4. Does this bar meet 2026 ANSI and OSHA standards?
Yes. The Super Anchor 1017C meets all current OSHA 1926.502 and ANSI Z359.18-17 Type D requirements. It is an industrial-grade anchorage point intended for certified fall arrest systems.
5. What is the benefit of the Safety Green powder coating?
Beyond providing corrosion resistance, the Safety Green color is a high-visibility indicator. It allows safety directors to confirm, from the ground or at a distance, that the framing crew has their fall-protection anchors properly installed in the open-framing zone.
6. Can this bar be used for vertical wall framing?
No. The 1017C is specifically designed for horizontal application on floor joists. Its geometry and testing parameters are based on the load forces of floor truss installation and decking.
7. How do I avoid common mistakes during installation?
- 1. Pin Verification: Ensure detent pins are fully seated and the wire lock is engaged. Never use the bar if a pin is missing or damaged.
- 2. Joist Span: Always span three joists. Never cantilever the bar or attach it to only two structural members.
- 3. Correct Setting: Double-check that all three legs are set to the same spacing increment (e.g., all set to 16") before attempting to mount the bar to the trusses.
