Product Information
Hollis SMS Weight System Plate (MPN 208.0042) is a rear-mounted ballast plate built specifically for the Hollis SMS 100 and Hollis SMS 75 sidemount harnesses, giving sidemount divers up to 18 lbs of extra trim weight carried low and centered on the rig.
Who it is for
This weight plate suits sidemount divers running a Hollis SMS 100 or SMS 75 harness who need added ballast without relying on a weight belt or pockets mounted elsewhere on the kit. Carrying the extra lead low and centered on the back of the harness helps hold a flat, horizontal trim.
Key details
- Weight capacity of up to 18 lbs total, 3 lbs per pocket
- Mounts to the rear of a single or dual tank kit via stainless steel book screws included with each Hollis SMS harness
- Corrosion-resistant construction built for saltwater use
- Carries ballast low and centered to help hold horizontal trim
Compatibility and sizing
The plate is designed to mount directly onto the Hollis SMS 100 and Hollis SMS 75 sidemount harnesses using the stainless steel book screws supplied with those harnesses, so no separate hardware purchase is required.

Frequently Asked Questions
How much weight does the Hollis SMS Weight Plate hold?
The plate supports up to 18 lbs of weight total, with each pocket rated for 3 lbs. This lets a sidemount diver add ballast in small increments to fine-tune trim without carrying extra lead elsewhere on the rig.
Is the Hollis SMS Weight Plate compatible with the SMS 75 harness?
Yes. The plate is designed to work with both the Hollis SMS 100 and the Hollis SMS 75 sidemount harnesses, mounting directly to the rear of either setup for a single or dual tank configuration.
What hardware do I need to mount the Hollis SMS Weight Plate?
No separate hardware purchase is needed. The plate mounts using stainless steel book screws, which are included with each Hollis SMS harness, so it attaches directly to an SMS 100 or SMS 75 you already own.
