The WB-400 Wire Keeper Form is a spring-tempered stainless wire keeper designed for compatible jig molds that accept WB400 (Do-It #2609) wire bait keeper inserts. When molded into a jighead, the WB-400 helps hold soft-plastic trailers in place, reducing trailer slippage and keeping your finished jighead build clean, secure, and consistent.
This small component makes a big difference for downsized and finesse builds. Ned rigs, Midwest finesse trailers, craws, and compact swimbaits can slide down the hook after repeated casts, skips, hops, and hooksets. A molded-in WB-400 wire keeper gives the trailer a secure gripping point while maintaining a clean, professional jighead profile — no cutting, bending, or modifications required.
The WB-400 features a precise 0.025" wire diameter and 0.38" overall length, the exact specification used by standard downsized jig heads. It drops directly into the designated wire slot of compatible Do-It style molds and holds securely in the cavity while you pour molten lead, setting flush once cooled.
The WB-400 wire keeper sold by LunkrBytes is proudly made in the U.S.A.
Sold by Weight
LunkrBytes sells these WB-400 wire keepers by weight for practical packaging and consistency. Each 3.5-gram package contains approximately 100 wires (a 17.5g pack contains approximately 500 wires, and a 35g pack approximately 1000 wires). Because the wires are packaged by weight, it is common for a 100-count package to contain approximately 99 to 101 pieces.

This product is sold as a loose, standalone lure-making component. It is not a finished jig, jighead, hook, artificial lure, bait, fly, or lure-making kit. Hooks, jigheads, skirts, collars, weed guards, molds, and soft plastics are sold separately unless otherwise stated.
