ISO Handles Attachment/Pair

Name: ISO Handles Attachment/Pair
Brand: Bullet Proof Fitness Equipment
Rating: 4.92 (4 reviews)

A pair of knurled handles from Bulletproof Fitness Equipment that turns the VTS Rack Attachment into an iso-lateral training system. Each 28.5mm handle – the diameter of a standard barbell – drops directly into the VTS’s existing barbell latch, so pressing and pulling movements can be trained one arm at a time to correct imbalances and build symmetrical strength, without any extra hardware or setup. The medium knurl was refined with community feedback for a balance of grip and comfort. This is the simplest, non-articulating handle in Bulletproof’s lineup – buyers wanting rotation or adjustable width/angle should look at the company’s 3D or 360-bearing handles instead. It works with the full VTS only, not VTS Lite or VTS Lite HOME.

Knurl	Medium
Quantity	Pair (2 handles)
Compatibility	VTS only (not compatible with VTS Lite or VTS Lite HOME)

What is a Rack Attachment?

What rack attachments are

Rack attachments bolt or pin onto a power rack or squat stand to expand what it can do — J-cups and safety arms/straps (the essentials), plus dip bars, a landmine, a lat pulldown, weight-plate storage, roller J-cups, and more. They turn a rack into a whole gym.

Compatibility comes first

An attachment must match your rack’s upright size (2x2, 2x3, or 3x3) and hole pattern/hardware (e.g. 5/8-in vs 1-in holes, Westside spacing). Attachments are usually series-specific — a Monster Lite J-cup won’t fit an Echo upright — so confirm the fit before buying.

A simple, well-regarded accessory: the ISO Handles swap into the VTS Rack Attachment’s existing barbell latch to enable isolateral pressing and pulling, and every GymRadar reviewer who has used them reports being satisfied, with the knurl repeatedly singled out as “just right.” Its standout dimension is build quality — reviewers report zero complaints and consistent praise for fit and finish. The weakest spot is versatility: this is the plain, non-articulating baseline handle in Bulletproof’s own lineup, with 3D and 360-bearing handles priced above it for buyers who want more angle control. Independent coverage is thin (GymRadar’s n=4 sample is the only rated source), so treat the near-perfect score as directionally reliable rather than exhaustively verified.

+Functionality: knurled 28.5mm handles drop directly into the VTS barbell latch, no extra hardware needed to enable isolateral pressing and pulling (Bulletproof product page; GymRadar reviews)
+Build quality: reviewers call them well made with no complaints, and say the knurl "is just right" (GymRadar reviews)
+Versatility: works for both pressing and pulling and lets each arm move independently to correct imbalances; one reviewer names it their top handle recommendation for the VTS platform (GymRadar review)
+Value: at $129.99, reviewers rate it near-perfect for the money, and Reddit users treat it as the presumed-default option when discussing VTS setups (GymRadar reviews; r/homegym)

−Durability: no independent long-term-use data — all four GymRadar reviews are near-term impressions with no wear issues reported yet
−Versatility: it's the simplest, non-articulating handle in Bulletproof's lineup — the founder describes it as the "traditional straight knurled" baseline option, so buyers wanting rotation or multi-angle grip need the pricier 3D or 360-bearing handles instead (Home Gym Con 2025 interview)
−Functionality: only compatible with the full VTS — not VTS Lite or VTS Lite HOME — so owners of the lighter trolley system can't use them (Bulletproof product page)
−Value: the rating rests on a small GymRadar sample (n=4) with no independent editorial review evaluating the handles specifically, so the near-perfect score carries limited outside corroboration
