Best Inline Fuse Holder 4 Gauge (2026)

An amplifier install is a Saturday job until the power wire needs protection. A fuse holder sits between the battery and the amp, and it is the part that cuts power when the current runs too high. The best inline fuse holder 4 gauge covers the holders made for that wire, and the picks here show the range: ANL and AGU holders, 100 Amp and 150 Amp fuses, and a 3-pack with three fuse sizes. Each listing states its fuse type, wire gauge and included fuses, so the choice comes down to fuse amps, wire fit and what comes in the box.

Compared on paper

Every rating comes from the brand’s listing and is not a shop test (gathered 11 November 2026). Where a listing contradicts itself, both figures are shown.

How the points were given

The Shop Score weighs performance, build, value, safety where it applies, and warranty. Performance weighs the most, because the fuse amps and wire fit decide whether a holder protects the circuit. Safety points come from named features such as flame-retardant materials and insulating covers. Scores come from the listing text, and the winners were chosen by score and by fit.

No score drops under 9.2 or climbs past 9.8; a tool’s place inside those bounds is set by its weighted point total.

What the listings tell you

We read 5 fuse holder listings for this guide. Two of the listings include a 150 Amp fuse, and 3 include a 100 Amp fuse. Four listings contradict themselves on gauge, fuse type or pack size, and none states a warranty term. Read the fuse and gauge lines, not just the title.

Buying guide: best inline fuse holder 4 gauge

Fuse type: ANL, AGU or mini ANL

Three of the listings name ANL holders, 1 names an AGU holder, and 1 names a mini ANL holder. The BOJACK AGU holder takes 10×38 mm AGU fuses, while the ANL holders take ANL fuses. Match the holder to the fuse type already in your install; see our automotive fuse vs circuit breaker guide for how fuses protect a circuit.

Fuse amps

The included fuses run from 60A to 150A: the RECOIL pack ships with 3 fuses each of 60A, 80A and 100A, the BOJACK holders ship with 100 Amp fuses, and the SIGANDG and InstallGear holders ship with 150 Amp fuses. Match the fuse amps to the circuit, and keep a spare fuse with the holder.

Wire gauge

Every pick here fits 4 gauge wire. The BOJACK ANL and InstallGear holders take 0/2/4 gauge, the SIGANDG takes 1/0 or 4 gauge, the RECOIL takes 4/8 gauge with a reducer, and the BOJACK AGU fits 4/6/8/10 gauge wire, per the bullets. Check the holder’s gauge range against your wire before ordering.

What comes in the box

The RECOIL pack ships with 3 holders and 3 fuses each of 60A, 80A and 100A. The BOJACK AGU ships with 2 fuses of 100 Amp. The BOJACK ANL, SIGANDG and InstallGear holders each ship with 1 fuse. Count the fuses before you order, so a blown fuse does not end the install.

Safety and the install

Flame-retardant materials and insulating covers are the safety features these listings name: the BOJACK ANL, BOJACK AGU and SIGANDG listings all name flame retardancy, and the RECOIL listing names a high-temperature polycarbonate base and cover for insulation and protection. The InstallGear listing names no safety feature. If the wiring is beyond a basic fuse swap, use a licensed electrician.

Garage Fit Check

• Wire: 4 gauge wire fits every pick here, so check the holder’s gauge range against your wire before ordering.
• Fuse amps: the included fuses run from 60A to 150A; match the fuse to the circuit, not to the holder.
• Space: the BOJACK AGU holder is 8.5 cm long with a 17 mm diameter and a 5 mm mounting hole; check the fit against your panel.
• Spares: the RECOIL 3-pack ships with 3 fuses each of 60A, 80A and 100A, and the BOJACK AGU ships with 2 fuses of 100A.
