Crosby Chain Repair & Connecting Links
Chain sling repairs require grade-matched hardware - a Grade 80 chain with a lower-grade connecting link inserted in a repair is a Grade 60 chain sling at that link. Crosby chain repair and connecting links are grade-rated to preserve the WLL of the chain assembly they go into, and carry the marking required by ASME B30.9-2018 (Slings) and NACM Welded Chain Specifications to keep the assembly documented.
About Crosby Chain Repair & Connecting Links
When a chain sling develops a damaged link - bent, cracked, or deformed beyond the rejection criteria in ASME B30.9-2018 (Slings) - the repair options are cutting out the damaged link and re-joining the chain with a connecting link, or retiring the assembly if the damage is extensive enough that repair is not appropriate.
Crosby chain repair links are the mechanically-closed, grade-rated links that allow the re-joining of Grade 80 and Grade 100 alloy chain sections after a damaged link is removed. The mechanical closure secures the link in the closed position before the assembly returns to service - no wire, tape, or secondary retention required.
Grade matching is the non-negotiable requirement. A repair link matches the chain grade (Grade 80 or Grade 100) to maintain the original assembly WLL.

Types of Crosby Chain Repair Hardware
Mechanically Closed Connecting Links (Grade 80)
Crosby Grade 80 mechanically-closed connecting links for chain repair - the same A-339 design as the connecting links in chain sling fabrication. The link body opens for chain installation, then the locking mechanism closes and secures the link body before service. Grade 80 rated and marked per ASME B30.9-2018 (Slings) and NACM.
Mechanically Closed Connecting Links (Grade 100)
Grade 100 versions for repair of Grade 100 chain assemblies. Same mechanically-closed design, rated to match Grade 100 chain capacity.
Crosby Chain Repair Link Sizes
Crosby chain repair links are sized to match standard alloy chain sizes - 7/32" through 1" link wire diameter for industrial chain sling assemblies.
Grade Rating:
- Grade 80: For repair of Grade 80 alloy chain sling assemblies
- Grade 100: For repair of Grade 100 alloy chain sling assemblies
Marking:
- Grade designation, WLL, and manufacturer ID per ASME B30.9-2018 (Slings) and NACM
Why Crosby for Chain Repair Links
Grade matching in chain repairs is the central technical requirement - the entire assembly WLL is determined by its weakest link, and a repair link that's a lower grade than the chain it joins becomes that weakest link. Crosby's Grade 80 and Grade 100 repair links carry the grade marking and WLL values that maintain assembly documentation integrity.
The mechanically-closed design means the link can't be re-opened in service without deliberate disassembly - the lock prevents the repair link from working open under cyclic loading.

Chain Repair Link Safety and Awareness
Chain repair connecting links fall under ASME B30.9-2018 (Slings) and NACM Welded Chain Specifications. OSHA 1910.184 and OSHA 1926.251 reference chain sling inspection and repair requirements.
Key awareness points:
- A chain sling with a damaged link warrants removal from service until the damaged link is removed and the chain is rejoined with a grade-matched connecting link - or the assembly is retired if the damage is too extensive for repair.
- Repair links are fully closed and mechanically locked before the assembly returns to service.
- A repaired chain sling should be re-inspected after repair before returning to service per ASME B30.9-2018 (Slings) initial inspection requirements.
- Chain sling repairs performed by unqualified persons or with non-grade-matched hardware are not acceptable in documented rigging programs.
Frequently Asked Questions
No. Chain repair requires a grade-matched connecting link - the repair link matches the chain's grade designation (Grade 80 or Grade 100). Installing a lower-grade connecting link in a Grade 80 chain assembly limits the assembly WLL to the lower-grade rating at that link. Crosby's Grade 80 and Grade 100 mechanically-closed repair links maintain the original assembly WLL when installed correctly.
ASME B30.9-2018 (Slings) covers chain sling inspection, rejection criteria, and repair requirements. NACM Welded Chain Specifications govern the hardware grade requirements. OSHA 1910.184 references chain sling use and inspection in general industry; OSHA 1926.251 applies to chain slings on jobsites.
