You’ve finally spent the money on a BaByliss PRO SkeletonFX or a Boost+. It’s shiny, it’s loud, and it hits like a freight train. But then you realize that for certain bulk removal or beard blending tasks, the bare blade is just too aggressive. You need guards. But here’s the thing: BaByliss PRO trimmer guards are a weirdly misunderstood accessory in the barbering world.
Most people assume any guard will fit any trimmer. They’re wrong.
Actually, the world of trimmer attachments is a bit of a minefield. If you’ve ever had a guard fly off mid-cut or heard that terrifying clack-clack-clack of the blade eating into the plastic, you know exactly what I mean. Getting the right fit isn't just about convenience; it’s about not ruining a $200 tool or, worse, your client’s hairline.
Why the Premium Guards are Actually Different
Standard guards are usually flimsy plastic. They bend. They heat up. Honestly, they’re kinda trash if you’re using them ten times a day. The official BaByliss PRO premium trimmer guards (often labeled under the Barberology line) are made from fiberglass-reinforced nylon.

Why does that matter?
Fiberglass reinforcement means the teeth don’t flex when you press against the skin. If a guard tooth flexes, the blade gets closer to the skin than intended. That’s how you get "stray" patches that are shorter than the rest of the blend. These premium versions also feature a gold metal clip. It’s not just for the "aesthetic" (though it does look cool on the GoldFX); that metal clip creates a mechanical lock that plastic tabs just can’t match.
The Compatibility Trap: What Fits What?
The biggest headache is figuring out which guards fit which model. BaByliss has a habit of releasing specialized versions, but for the most part, the premium trimmer guard set (Product FXPTG) is designed for:
- FX787 Models: This is the SkeletonFX, GoldFX, SilverFX, etc.
- FX726: The Lo-ProFX trimmer.
- FX797: The newer FX3 series.
If you are trying to shove these onto a different brand, like a Wahl Detailer or an Andis T-Outliner, stop. Just stop. The blade width on the BaByliss T-blades is specific. Even within the BaByliss ecosystem, some older or "home" models might use a slide-on plastic guard that won't work with the metal-clip versions.

The premium set usually comes with four specific sizes:
- .5 (1/16") or 1.5mm
- 1 (1/8") or 3mm
- 1.5 (3/16") or 4.8mm
- 2 (1/4") or 6mm
It’s a small range. You aren't going to do a full haircut with these. These are for "hybrid" work—blending the beard into the sideburns or cleaning up the bulk around the ears before you go in for the detail work.
The Zero-Gap Nightmare
Here is a dirty secret: if you zero-gap your trimmers to the absolute limit, your guards might fail you.
When you zero-gap a BaByliss PRO blade, you’re moving the cutting blade closer to the edge of the stationary blade. If you go too far, the vibrating teeth can actually strike the inside of the trimmer guard. You’ll hear a high-pitched buzzing or a grinding sound.
I’ve seen barbers "melt" the inside of a #.5 guard because the blade was vibrating against the plastic. If this is happening to you, you have two choices. You can back off the zero-gap just a hair (we're talking microns here), or you can check if the guard is seated perfectly flush. Sometimes a tiny bit of hair buildup under the clip prevents the guard from sitting level, causing the "strike."
Pro Tips for Longevity
Don't just toss these in a jar of Barbicide and forget about them. Fiberglass nylon is tough, but the metal clips can eventually lose their tension if you’re constantly prying them off with too much force.
- The Thumb Snap: When putting them on, hook the front of the blade first, then snap the metal clip over the back. Don't try to slide them on from the side.
- Heat Check: Even though they're reinforced, if you're running a high-torque motor for 20 minutes, the blade gets hot. Plastic and heat aren't friends. Pop the guard off between uses to let the blade breathe.
- Deep Clean: Once a week, take a toothbrush to the "tracks" of the guard. Skin oils and tiny hair splinters act like sandpaper over time.
Transitioning to Hybrid Cutting
Many barbers are moving away from using clippers for everything. They use the BaByliss PRO trimmer guards to handle the lower sections of a taper. It’s faster. The smaller head of a trimmer allows for better visibility than a bulky clipper.
If you're struggling to blend the #0 open on a clipper into the #1 guard, try using the #.5 trimmer guard on your SkeletonFX. Because the trimmer blade is thinner than a clipper blade, a #.5 trimmer guard actually cuts slightly closer than a #.5 clipper guard. It’s that "secret" bridge between a bald line and the first step of a fade.

Real-World Limitations
Let’s be real for a second. These guards are expensive for what they are—essentially four pieces of plastic and some wire. You’re paying for the fit. Third-party guards from Amazon or AliExpress often claim to fit the FX787, and while they might "click" on, they often have "play" or wiggle room.
Wiggle room is the enemy. If a guard moves 1mm while you’re mid-stroke on a beard, you’ve just created a divot that takes three weeks to grow back. Stick to the OEM (Original Equipment Manufacturer) guards for these specific tools. The cost of one bad haircut is way higher than the $20 for the proper guard set.
Maintenance Steps to Take Now
- Inspect your clips: Check the gold metal clip on your current guards. If it’s bent outward, use a pair of needle-nose pliers to gently (very gently) crimp it back for a tighter fit.
- Verify your blade alignment: Ensure your T-blade isn't crooked. A crooked blade is the #1 cause of guards "buzzing" on one side but not the other.
- Match your set: If you’re using the FX3, make sure you aren't using the old plastic-only guards. The FX3 runs at a higher RPM, and the vibration will shake loose anything that isn't metal-clipped.
Keep the fiberglass teeth clean, ensure your zero-gap isn't too aggressive for the plastic housing, and always seat the front of the blade before snapping the back.
