The Powerblock® Stainless Knurled Handles are an aftermarket replacement handle for PowerBlock adjustable dumbbells, sold by JD Gym Equipped, that swap PowerBlock’s stock rubber grips for a pair of solid 1.25” stainless-steel handles with an aggressive volcano knurl.

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.

The Powerblock® Stainless Knurled Handles are a well-reviewed upgrade for owners tired of PowerBlock’s stock rubber grips, with every independent source praising the aggressive volcano knurl for grip and feel — one reviewer scored it 4.7/5 overall and won’t go back to rubber. Functionality is the clear standout: a solid stainless-steel bar that installs with just an Allen wrench and fits most PowerBlock lines (USA, Pro, Sport). The weakest point is durability data — the handles aren’t galvanized, drawing a rust caution in humid climates, and independent coverage is thin (two written reviews plus one installation video), so there’s limited long-term wear evidence beyond initial impressions.

+Functionality: aggressive volcano knurl gives noticeably better grip than PowerBlock's stock rubber handles, described as inspiring confidence on heavier lifts (King of the Gym)
+Build quality: solid 1.25" stainless steel bar, made in the USA with US stainless, replacing the injection-molded rubber grips PowerBlock ships stock (JD Gym Equipped product listing)
+Versatility: fits most PowerBlock dumbbell lines (USA, Pro, Sport models) as a bolt-on upgrade (JD Gym Equipped; King of the Gym)
+Value: priced competitively enough that it undercuts custom machine-shop alternatives for comparable knurl quality (Shredded Dad)
+Functionality: install requires only an Allen wrench, no special tools (JD Gym Equipped; installation video)

−Durability: handles are not galvanized, so King of the Gym flags a rust risk in humid environments
−Compatibility: buyer must confirm the exact PowerBlock model before ordering — the listing recommends emailing a photo, and sources differ on whether Elite-series dumbbells fit (JD Gym Equipped vs. Shredded Dad)
−Build quality: adds a modest amount of weight per handle (+11.4 oz on the USA model, +10.16 oz on Pro & Sport models), a minor trade-off for the grip upgrade (JD Gym Equipped)
−Functionality: independent coverage is thin — two written reviews and one installation video — so there's limited long-term-use data beyond initial impressions (knowledge base coverage)
