SLM-6 Monster Weight Stack Slinger

The SLM-6 is a unique variation of our standard Monster Weight Stack Slinger™, designed specifically for use with RM-6 Monster Power Racks. Ideal for users who have their rack positioned near a wall, this new set-up enables (a) the weight stack to sit conveniently in the smaller 24” back section of an RM-6 unit, and (b) the user to still work freely off the front of the rack, utilizing the kit’s longer cable and additional pulley.

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.
