The correct method of securing a weld-on pivot link is a [t weld] which consists of a [perpendicular](/source/Perpendicular) vee butt joint secured to the billet using a [butt weld](/source/Butt_weld) or [fusion weld](/source/Fusion_weld). A **D-ring** is an item of [hardware](/source/Household_hardware), usually a tie-down metal ring shaped like a capital [letter 'D'](/source/D) used primarily as a lashing or attachment point. The term is found interchangeably spelled in different forms, such as: ***D ring***, ***D-ring*** or ***dee-ring***. A D-ring may be used at the end of a leather or fabric strap, or may be secured to a surface with a metal or fabric strap; though there are D-rings with a middle body designed to be welded to steel. Ideally, a D-ring swings freely after it has been secured. D-rings may vary in composition, geometry, weight, finish and load (rated) capacity. Though there are differences, a weld-on pivoting link is commonly called a D-ring. To minimize obstruction when the D-ring is not in use, recessed tie-down rings are designed that accommodate the D-ring so it is flush to the surface. There are some non-recessed designs that have an adhesive base. Work load limits are specified where appropriate. For D-rings used in the bed of a truck to secure loads, regular preventative maintenance is important to avoid costly repairs.[1] D-rings may be made of plastic for applications such as fixtures for straps for [hiking equipment](/source/Hiking_equipment).[2] ## Common uses A D ring binder Applications of D-rings include: - For light loading applications such as clothing and [luggage](/source/Luggage), D-rings made of plastics such as [nylon](/source/Nylon) may be used, as they weigh less and are impervious to [rusting](/source/Rust). - As a component for lacing up items of footwear like hiking boots or any adjacent heavy-duty footwear. - At the end of a tow-rope or chain, to allow the creation a bow around an item or part of an item that is being towed. - With a chain to tether a [boat](/source/Boat) to a [dock](/source/Dock_(maritime)) or [tree](/source/Tree) when it is being moored. - In [theatres](/source/Theatre), commonly used where a piece of [scenery](/source/Scenery) has to be lifted or "flown". D-rings are attached to the tops or bottoms of [flats](/source/Flats_(theatre)) with a "drift line" and turnbuckle attached to adjust the "trim". - A D-ring on an [M16](/source/M16_rifle) or variant type rifle is used to increase the pressure on the extractor and reduce malfunctions. This D-ring is a rubber [grommet](/source/Grommet) shaped like a "D" and fits over the extractor spring adding tension to it. - On [breathing sets](/source/Scuba_set) and scuba divers' [buoyancy compensators](/source/Buoyancy_compensator_(diving)) - A [bit ring](/source/Bit_ring) used on the bit of a horse. - A D-ring [carabiner](/source/Carabiner) has a section which opens and can be secured, to attach a rope for climbing or caving or to attach other items.[3][4] - A part of a [saddle](/source/Saddle) (see [saddle#D-ring](/source/Saddle#D-ring)) - A D-ring binder is a type of [ring binder](/source/Ring_binder) which uses D-shaped rings to accommodate larger documents or more pages.[5] - To attach a leash or tag to a [collar](/source/Collar_(animal)) or [pet harness](/source/Pet_harness),[6] or to a waist belt, either for dog walking or for sports where the dog is intended to pull.[7] - On a [prisoner transport belt](/source/Body_belt) to accommodate a pair of [handcuffs](/source/Handcuffs) - As part of [BDSM](/source/BDSM) restraints, clothing, or furniture, to act as an attachment point for rope or chain - For hanging a [framed](/source/Picture_frame) picture, D-rings attached to a small metal plate with a hole in it are used: the D-ring is attached to the frame with a screw through the hole, and the wire to hang the picture passes through the D-ring.[8] - Two adjacent D-rings can be used as an adjustable fastener for a strap in clothing such as [overalls](/source/Overalls).[9] ## References 1. **[^](#cite_ref-1)** ["Don't Let D-rings Be "D" Problem"](https://www.dvidshub.net/publication/issues/70969#page=9). *[Preventive Maintenance Monthly](/source/Preventive_Maintenance_Monthly)* (738): 15.
