Efficient Installation and Waterproof Performance
The D-Minus Anchor installs rapidly, requiring just six factory-supplied stainless steel spiral shank nails or optional #12 screws. Designed for versatile deployment, this anchor is compatible with both vented and non-vented ridge caps. Each anchor in this 10-pack includes a high-performance butyl strip to create a gasketed, waterproof seal, ensuring the roof deck remains protected from moisture intrusion. This discreet design is nearly invisible once installed, making it a favorite for residential reroofing and retrofit applications where aesthetics are a priority.
Fall Indicator Technology and Safety Compliance
Built for rigorous job site demands, the Super Anchor 1075 features a fall indicator stem that provides a clear visual warning if the anchor has been subjected to in-service loading. This anchor is OSHA-rated for 5,000 lbs and complies with all relevant ANSI standards for fall arrest. Its connector hole is specifically sized to accept all 3,600 lb gate strength connectors, ensuring compatibility with standard lifelines and lanyards. Whether used as a permanent, temporary, or disposable solution, the D-Minus delivers A+ safety performance at an economical price point.

Super Anchor 1075 D-Minus FAQ
1. Can the D-Minus anchor be installed on a finished roof?
Yes. The D-Minus is an excellent retrofit solution. It is designed to be installed over shingles and is compatible with ridge caps. If you need a specialized retrofit option for tile roofs, we recommend the Super Anchor 2815-T Tile Anchor.
2. How does the Fall Indicator work?
The D-Minus includes a physical indicator stem. If the anchor is involved in a fall, the stem will deform or deploy, signaling that the anchor has been loaded and must be removed from service immediately. Refer to the Super Anchor D-Minus Instruction Manual for visual inspection cues.
3. Is the butyl flashing necessary for every installation?
For permanent installations, yes. The butyl strip creates a watertight seal around the fasteners to prevent leaks. In this 10-pack, butyl is included. If you are using these as temporary anchors during a single-day project, the butyl is optional but recommended for peace of mind.
4. What is the recommended spacing for these anchors?
Super Anchor recommends a maximum spacing of 12 feet on-center along the ridge to ensure that a worker can remain in fall restraint while moving across the roof surface.
5. Can more than one person tie off to a single D-Minus?
No. The D-Minus is a single-user fall arrest anchor. Connecting multiple workers to one anchor violates OSHA regulations and significantly increases the risk of structural failure during a fall event.
6. Does this anchor work on standing seam metal roofs?
While it can be nailed into the wood substrate of a metal roof, we highly recommend Standing Seam Roof Anchors to avoid creating penetrations in your metal panels.
7. How do I avoid common mistakes during installation?
- 1. Structural Attachment: Fasteners must penetrate into a structural rafter or ridge beam. Nailing into the plywood deck alone will not provide the required 5,000 lb strength.
- 2. Correct Fasteners: Use only the provided stainless steel spiral shank nails. Smooth nails do not provide the same pull-out resistance and are not compliant.
- 3. Over-Painting: While the anchor is paintable, ensure you do not apply paint so thick that it clogs the fall indicator stem or the connector hole.
