Body-Solid power rack attachment compatibility trips people up because not every attachment fits every rack family — a lat attachment built for a Smith machine won't bolt onto a power rack, and a leg press attachment built for an EXM2500 station is a different mount than one built for a GPR or SPR rack. This guide covers only true power-rack-family attachments, split by which base rack they actually fit: the GPR-series rack (like the GPR378) and its functional trainer attachments, versus the SPR1000-series racks and their functional trainer attachments.
GPR378 Power Rack with Lat Attachment — The GPR-Family Base Rack
Price: $900 (range $1,000–$1,300) | Mainframe: Heavy-duty 11-gauge steel, 3"x3" | Weight Capacity: 2,000 lbs. | Dimensions: 50"L x 46"W x 80"H (72"L x 46"W x 84"H with Lat Attachment) | Cables: 2,200 lb. test aircraft cable
The GPR378 is the base rack in Body-Solid's GPR power rack family, built on an 11-gauge 3"x3" steel mainframe with a 2,000 lb. weight capacity. It already ships with a lat attachment and 2,200 lb.-rated aircraft cables, and its footprint grows from 50" to 72" long once that lat attachment is mounted. This is the rack the GPRFT and GPRFTS attachments below are built to fit.
GPR-Family Functional Trainer Attachments: GPRFT and GPRFTS
GPRFT — Price: $1,495 | Weight Capacity: 600 lbs. | Product Weight: 190 lbs. | Footprint: 77"L x 74"W x 81.25"H
GPRFTS — Price: $2,795 | Weight Stacks: Two 210 lbs., 2:1 ratio | Product Weight: 625 lbs. | Footprint: 77"L x 74"W
Both the GPRFT and GPRFTS are built to mount to a GPR-family rack like the GPR378, turning it into a functional trainer. The GPRFT is the lighter, more affordable option at 190 lbs. with a 600 lb. weight capacity if you're loading it with plates or bands, while the GPRFTS adds two self-contained 210 lb. weight stacks at a 2:1 ratio for faster, stack-based training — at more than triple the product weight and a higher price to match.
Best for: GPR-family rack owners choosing between plate/band-based versatility (GPRFT) and stack-based convenience (GPRFTS).
SPR1000-Family Functional Trainer Attachments: SPRFTS and SPRFTS/3
SPRFTS — Price: $4,250 | Weight Stacks: Dual 210 lbs. (upgradable to 310 lbs.) | Product Weight: 672 lbs. | Dimensions: 91"L x 58"W x 92"H
SPRFTS/3 — Price: $4,795 | Weight Stacks: Dual 310 lbs., 2:1 ratio | Product Weight: 672 lbs. | Dimensions: 91"L x 58"W x 92"H
The SPRFTS and SPRFTS/3 are built for Body-Solid's larger SPR1000-family racks, not the GPR378 — they share the same 672 lb. product weight and 91"x58"x92" footprint, with the only real difference being weight stack size out of the box. The standard SPRFTS ships with dual 210 lb. stacks that can be upgraded to 310 lbs. later, while the SPRFTS/3 ships with 310 lb. stacks already installed, saving you the upgrade step if you know you'll need the extra capacity from day one.
Best for: SPR1000-family rack owners who want a functional trainer attachment sized for a bigger commercial installation than the GPR line supports.

Frequently Asked Questions
What is the Body-Solid GLA348B lat attachment price, and does it fit a power rack?
The GLA348B is $989, but it's built specifically as a Series 7 Smith machine lat attachment — it fits Smith machines, not the GPR or SPR power racks covered in this guide.
What is the Body-Solid GLP2500 leg press attachment review?
The GLP2500 is a premium leg press attachment priced at $1,285, using a 1:2 ratio (a 210 lb. stack delivers 420 lbs. of resistance). It's built to mount to Body-Solid's EXM2500 station, not to a GPR or SPR power rack.
Is there a Smith machine lat pulldown attachment?
Yes — Body-Solid's GLA348B is a lat pulldown attachment built for the Series 7 Smith machine specifically, separate from the power-rack functional trainer attachments in this guide.
What is the EXM2500 leg press attachment?
The GLP2500 is Body-Solid's leg press attachment built for the EXM2500 multi-station gym, using a 1:2 leverage ratio, and it's not interchangeable with GPR or SPR power rack attachments.
How do I know which power rack attachments guide applies to my rack?
Check your rack family first: the GPR378 and other GPR-series racks pair with the GPRFT and GPRFTS attachments, while SPR1000-series racks pair with the SPRFTS and SPRFTS/3 attachments. Mixing families isn't supported.
