Understanding the Dave Graham Repair Manual
The Dave Graham Repair Manual is a climbing community resource focused on bolting, anchor building, and trad gear maintenance. Dave Graham is a well-known professional climber who has put up some of the hardest trad routes in the world, and his approach to route development and hardware upkeep has been documented in this kind of reference material. It covers things like which bolts to use where, how to set anchors properly, and how to maintain gear so it doesn't fail on a big wall or a hard climb. The manual isn't an official product from a single company. It's more of a living document, passed around on climbing forums and Google Docs, updated by various contributors over the years. You'll find sections on epoxy vs. mechanical anchors, glue-in bolt placement, cleaning old gear, and the practical realities of building anchors in different rock types.
How to Use the Dave Graham Repair Manual
Start by identifying what you're actually trying to fix or build. The manual is organized by category—bolting, anchors, trad gear, ice screws, etrangs—and each section has its own set of guidelines. I usually pull up the relevant section before I head out to a project, then reference it while working rather than trying to memorize it all beforehand. That approach has worked fine for me over the years. One thing the manual gets right, and I've seen this in practice, is the emphasis on bolt type matching the rock. You will see people put stainless steel glue-ins into sandstone and wonder why they fall out two seasons later. The manual walks through the corrosion rates, pullout strengths, and appropriate applications for different bolt materials in granite, limestone, sandstone, and volcanic rock. It's not always precise about exact measurements—you'll still need to check manufacturer specs—but it gives you the right starting point. I had a situation a few years ago where I was replacing legacy bolts on a route that had been climbed for twenty-plus years. The original bolts were titanium hangerless installations, and the new bolts I was installing were 3/8 inch by four-inch thread-ins with aluminum hangers. The issue was that the old bolts weren't just corroded—they were backed out from freeze-thaw cycles in a granite crack. I used the manual's guidance on bolt spacing and hanger orientation, but the real workaround came from checking the surrounding rock first. I tapped each hole with a hammer to confirm it wasn't cracked, and I backed out any suspect bolts completely before threading in the new ones. The manual doesn't cover this exact edge case, but the general principle about evaluating host rock before committing to a new bolt held up. The route is still solid five years later.
When you're working through the anchor section, pay attention to the redundancy discussion. A lot of climbers treat equalization as the end goal, but the manual makes it clear that equalization is only useful if your anchor points are independently sound. I've seen too many top-rope anchors built with two chains running off a single degraded bolt. The manual recommends treating every piece as if it could be the only piece holding you, which means you should always assume worst-case load direction when building your anchor.

Common Mistakes People Make
The most frequent error I see is treating the manual as a one-size-fits-all document. Rock types matter enormously. What works in Vermont granite is a disaster in Florida limestone, and vice versa. The manual flags this, but people skip past the rock-type tables because they want to get to the quick instructions. Another mistake is using the manual for ice climbing hardware without realizing how outdated some of the ice-specific sections are. Ice screw placement and glacier travel protocols have evolved. The manual is stronger on rock climbing than on alpine or ice work. The manual also doesn't do a great job covering modern gear like the Petzl Pro Traxion or other rescue systems. If you're doing high-angle rescue work or technical caving, you'll need to supplement with manufacturer manuals and current trade publications. The Dave Graham Repair Manual is best treated as a foundational reference, not the final word on every climbing maintenance topic.
Where to Find It
You can usually find the Dave Graham Repair Manual as a free PDF on climbing forum threads, particularly on sites like r/climbing, UKClimbing forums, and the Mountain Project community boards. It's also been archived on Google Drive by various climbing groups. Search for the full title along with "PDF" or "doc" and you should find the current version. Be aware that older copies float around, so check the document date and look for the most recent edits. The manual gets updated, but not on a strict schedule. If you're serious about route building or anchor work, reading through the manual cover to cover takes maybe an hour. The real value comes from using it alongside the manufacturer specs for whatever hardware you're actually installing. The manual tells you what to think about. The specs tell you exactly how much force a bolt can handle. Both matter.
