Average Joe Innovations Knurled Grips

Name: Average Joe Innovations Knurled Grips
Brand: Average Joe Innovations
Rating: 4.91 (7 reviews)

Average Joe Innovations’ Knurled Grips are an aftermarket replacement grip for PowerBlock adjustable dumbbells, sold as “The Grip that Fits.” Each pair is machined from solid 316 stainless steel – not a coating over regular steel like PowerBlock’s factory grips – in four thicknesses (25mm, 30mm, 35mm, 40mm) and four knurl aggressiveness levels (light, light-medium, medium-aggressive, aggressive), for 16 total combinations. They’re compatible with 34+ PowerBlock models over 40 lb, including the Sport, Elite, Professional, and Commercial lines from 1993 to present, but do not fit models under 40 lb or the Personal Plus. Installation adds roughly 0.5-1.5 lb per dumbbell depending on the thickness chosen.

GymRadar owners rate the grips 4.91/5 across 7 reviews (5.00 for performance and build quality, 4.71 for value), describing them as a “perfect upgrade” that makes PowerBlock dumbbells “feel more solid” at sizes ranging from 30mm to 40mm. In its own installation and comparison videos, the manufacturer contrasts its solid 316 stainless steel against PowerBlock’s chrome-coated OEM grips, showing the factory coating rusting and peeling with use – a durability claim worth treating as manufacturer-sourced rather than independently verified, since no third-party long-term wear testing exists yet.

What is a Miscellaneou?

What’s in Miscellaneous

This is the catch-all for the conditioning tools and accessories that don’t fit a single equipment class — weighted vests and plate carriers, medicine and slam balls, plyo boxes, ab mats, and the odds and ends that round out a garage gym. Items land here because their job (loaded carries, jumps, core work) cuts across the categories rather than sitting neatly inside one.

Who it’s for

Anyone filling in the gaps around the big pieces. If you already have a rack, bar, and plates, this is where you find the vest for rucking and weighted push-ups, the ball for slams and wall throws, or the box for step-ups and box jumps. Match the tool to the training you actually do — a plate carrier for conditioning and rucking, plyo boxes for explosive work — rather than buying the whole shelf.

Average Joe’s aftermarket knurled grips are a well-regarded upgrade for PowerBlock adjustable dumbbells, with GymRadar owners consistently praising the build quality — solid 316 stainless steel versus PowerBlock’s coated steel OEM grips, which the maker’s own comparison footage shows rusting and peeling over time. Value lands well too: at $100-130 a pair it undercuts or matches PowerBlock’s own factory-replacement pricing while offering 16 thickness/knurl combinations. The weakest spot is durability — beyond the manufacturer’s own claims, there’s no independent long-term wear data, and coverage is thin (7 GymRadar reviews, no expert press).

+Build quality: solid 316 stainless steel construction, not a coating over regular steel (knurledgrips.com, GymRadar reviewer Big Ashley)
+Durability: 316-grade stainless resists sweat/chloride corrosion better than PowerBlock's OEM chrome-coated grips, which the maker's own footage shows rusting and peeling (YouTube: Average Joe Innovations)
+Value: $100-130/pair matches or undercuts PowerBlock's own aftermarket grip pricing (knurledgrips.com, GymRadar value score 4.71/5)
+Versatility: 4 thicknesses (25/30/35/40mm) x 4 knurl aggressiveness levels = 16 combinations, fits 34+ PowerBlock models (knurledgrips.com)
+Functionality: users report a noticeably more solid, secure feel under load after installing (GymRadar reviewer That Big Mofo Guy)

−Durability: no independent long-term wear testing beyond the manufacturer's own comparison claims
−Versatility: does not fit PowerBlock models under 40 lbs or the Personal Plus line (knurledgrips.com)
−Value: a meaningful add-on cost ($100-130) on top of an already-owned dumbbell set
−Functionality: adds 0.5-1.5 lbs per dumbbell, changing the total loaded weight (knurledgrips.com)
