Comparing the GLA348B vs GLA348BS comes down to one core question: do you want a plate-loaded lat attachment, or one with its own built-in weight stack? Both are Series 7 Smith Machine lat attachments designed to add lat pulldown and related pulling movements to your Smith machine setup — the difference is entirely in how you load the resistance.
GLA348B Series 7 Smith Machine Lat Attachment
Price: $989 | Type: Rack Attachment | Loading: Plate loaded | Weight: 75 lbs. | Dimensions: 78"L x 69"W x 84"H
The GLA348B Series 7 Smith Machine Lat Attachment is the plate-loaded option: you load your own Olympic or standard plates to set resistance rather than pinning a stack. At just 75 lbs., it's dramatically lighter than the stack-equipped version and the lower-priced of the two at $989, backed by Body-Solid's commercial/lifetime warranty.
Plate loading means unlimited resistance ceiling (as much weight as you're willing to load) and a lower purchase price, at the cost of needing loose plates on hand and the extra step of loading/unloading between users.
Best for: buyers who already have loose plates, want the lowest entry price, and don't mind manually loading weight.
GLA348BS Series 7 Smith Machine Lat Attachment with Stack
Price: $1,285 | Type: Rack Attachment | Loading: Built-in 210 lb. precision machined alloy steel weight stack | Weight: 285 lbs. including the stack
The GLA348BS Series 7 Smith Machine Lat Attachment with Stack adds a precision machined 210 lb. alloy steel weight stack directly to the attachment, so there's no plate loading required — just pin your resistance and go. That convenience adds both cost ($1,285, a $296 premium over the GLA348B) and weight (285 lbs. total including the stack versus 75 lbs. for the plate-loaded version).
The built-in stack makes the GLA348BS the faster option for multi-user or commercial settings where quick resistance changes matter more than saving on upfront cost.
Best for: commercial facilities or multi-user households that want quick, pin-selected resistance changes without loading plates.
Quick Comparison Chart
| Model | Price | Key Spec | Best For |
|---|---|---|---|
| GLA348B | $989 | Plate loaded, 75 lbs. | Lowest cost, already own plates |
| GLA348BS | $1,285 | Built-in 210 lb. stack, 285 lbs. total | Fast, pin-selected resistance changes |
Plate-Loaded vs. Built-In Stack: Which Should You Choose?
Both the GLA348B and GLA348BS are designed as Series 7 Smith machine attachments, so the choice isn't about compatibility — it's about how you want to load resistance. If you already have plates and want to save $296, the GLA348B gets the job done. If you'd rather have a self-contained 210 lb. stack and don't want to manage loose plates, the GLA348BS is worth the extra cost and weight.
