The thimble's curved groove spreads the load evenly around the loop and keeps its shape open and round rather than crushed flat, so the rope holds its strength and lasts longer at the termination point.\u003c\/p\u003e\n\u003cp\u003eDIN 6899 covers two forms of wire rope thimble. Form B (this one) is the standard light-pattern thimble used for typical wire rope work; form A is the heavier pattern used with larger chain and heavier rigging gear. Made from galvanised steel, this thimble suits outdoor and general engineering environments where corrosion resistance matters.\u003c\/p\u003e\n\u003cp\u003eEach size in the range is proportioned specifically to its rope diameter: overall length, eye width and eye length all increase together as the rope gets thicker, rather than a handful of eye sizes being shared across multiple rope diameters. That means the eye on a 6mm thimble is genuinely different from the eye on an 8mm or 10mm thimble, even where the difference looks small on paper, so it pays to check the dimensions below rather than assume nearby sizes are interchangeable. Metric measurements are given throughout, with an approximate imperial (inch) equivalent alongside each one for cross-referencing against imperial-spec rope or fittings.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufactured to DIN 6899, form B, the standard light-pattern wire rope thimble profile, as distinct

protecting the loop where it's spliced or clamped around a shackle, hook, ring or anchor point, so the rope isn't taking the full load against bare metal.\u003c\/li\u003e\n\u003cli\u003eGeneral rigging: anywhere a wire rope needs a durable, low-wear loop rather than a bare bend against a connecting fitting.\u003c\/li\u003e\n\u003cli\u003eGeneral lifting applications: slings, lifting rope assemblies and tie-down loops where the rope eye takes repeated load and repeated handling.\u003c\/li\u003e\n\u003cli\u003eFencing and balustrade wire installations: looping tensioned wire rope around posts, uprights or fixing points without crushing the wire out of shape at the anchor point.\u003c\/li\u003e\n\u003cli\u003eAgricultural and general engineering rigging: wherever a wire rope loop is formed and needs protecting from wear and abrasion over repeated use.\u003c\/li\u003e\n\u003cli\u003eAnywhere a rope loop needs protecting from wear and abrasion, and needs to keep its round shape rather than being pulled flat under tension.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Guidance\u003c\/h3\u003e\n\u003cp\u003eFit the thimble as part of forming the rope termination itself, not after the loop is already closed:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLoop the rope around the thimble's outer groove so the thimble sits inside the loop, following its curved profile.\u003c\/li\u003e\n\u003cli\u003eSecure the loop with wire rope clamps (see our matching DIN 741 clamps) or a swaged\/spliced termination; the thimble isn't a standalone fitting, it stays inside the finished loop and is held in place by the termination itself.\u003c\/li\u003e\n\u003cli\u003eMatch the thimble size to your rope diameter first; sizes are not generally interchangeable between adjacent rope diameters, as both the groove and eye dimensions change together.\u003c\/li\u003e\n\u003cli\u003eOnce the loop is formed, choose any connecting shackle, hook or ring to suit the thimble's eye width and eye length, not the rope diameter alone.\u003c\/li\u003e\n\u003cli\u003eOn rigging and lifting applications in particular, check the loop periodically for wear or deformation, since the thimble's role is precisely to take that wear so the rope itself doesn't have to.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOrder before 2pm Mon–Fri for same-day
