Product Details
Melba SB-Weight Clip-On Ballast
Use the SB-Weight when plastic barriers and temporary sign frames need more weight at the base. It is a fixed, reusable ballast unit that one person can clip on, lift off and stack. Each unit is moulded to a set weight, so you know what you are adding at every point on the run.
The yellow clip hooks the weight over the bottom rail of a compatible plastic barrier. The base also sits on the legs of Melba Swintex Q-Sign frames. It suits traffic management teams, streetworks contractors and hire fleets that want one ballast line for barriers and sign set-ups instead of loose sandbags.
Barrier fit depends on the rail profile, so check your barriers against the clip before ordering in volume. The barrier, sign frame and sign face are not included.
Key Features
- Clip-on fitting: The yellow clip hooks over a barrier bottom rail. The weight is attached to the barrier rather than placed loose beside it.
- Q-Sign compatible base: Fits the full Melba Swintex Q-Sign range, so one ballast product can serve both sign frames and barriers.
- Fixed moulded weight: Approximately 7.35kg per unit, so you can plan ballast by unit count instead of estimating sandbag fill.
- Stackable: Units stack to add weight at the same point when one weight is not enough.
- Single-man lift: The ergonomic handle lets one person move and reposition weights between set-ups.
- Recycled PVC with embossing option: The base is made from recycled PVC and can be embossed with company branding to identify fleet stock.

Compatibility And Accessory Guide
The SB-Weight is itself an accessory. What you need is a compatible barrier or sign frame, plus enough weights for each point on the run
| Item | Status | Why It Matters | Notes |
|---|---|---|---|
| Plastic barrier or Q-Sign frame | Required, not included | The weight needs a rail to clip onto or a frame leg to sit on. | Order barriers with the weights to keep one delivery. |
| Melba Swintex Q-Sign range | Compatible | The base is made to fit the full Q-Sign range. | Weights per frame depend on the sign face. |
| Utility Barrier | Confirm before ordering | Same manufacturer as the SB-Weight. | Ask our team to confirm clip fit. |
| Chapter 8 plastic barriers | Confirm before ordering | Rail and foot profiles differ between barrier brands. | Send us the barrier make and model. |
| Additional SB-Weights | Optional | Stacking adds weight at the same point. | Keep stacks level and seated correctly. |
| Chapter 8 stillages | Optional | Stores and moves the plastic barriers the weights are used with. | Available in 20 and 40 barrier sizes. |
Alternative Products To Consider
| Product | Weight | Choose it when |
|---|---|---|
| Barrier Ballast Block | 16kg | You need more weight per unit for pedestrian barrier runs. |
| Barrier Ballast Bag | 10kg | You prefer a bag format for barrier ballast. |
| Barrier Ballast DropBlock | Ask our team | Your barrier is not suited to the SB-Weight clip and you need a different ballast format. |
What does the SB-Weight fit?
It fits the Melba Swintex Q-Sign range, sitting on the frame legs. It also clips to plastic barriers, with the yellow clip hooked over the bottom rail.
Barrier rail profiles vary between manufacturers and models, so check the fit before ordering for a full barrier fleet. Send us the barrier make and model and our team can confirm.
How many SB-Weights do I need per barrier or sign?
There is no single figure. The amount depends on:
- the barrier or sign frame
- the size of the sign face
- how exposed the site is
- the ballast guidance from the barrier or sign manufacturer
Work from that guidance and your site risk assessment. Then use the unit weight to calculate how many SB-Weights you need at each point. For larger set-ups, call us on 0330 056 4420 and we can help plan quantities.
Can SB-Weights be stacked?
Yes. The weights are designed to stack, so you can add weight at one point without switching to a different type of ballast. Make sure each stack is level and seated correctly before leaving the set-up.
Should I choose the SB-Weight or the 16kg Barrier Ballast Block?
Choose the SB-Weight for any of these needs:
- a clip-on weight for plastic barriers
- a base weight for Q-Sign frames
- weights that one person will reposition often
The 16kg Barrier Ballast Block carries more weight per unit and sits within our pedestrian barrier ballast range. If you are unsure which suits your barriers, contact our team before ordering.
Is the SB-Weight a replacement for sandbags?
It can replace sandbags wherever the barrier or sign frame takes the clip or base. Each unit is a solid moulded weight, so there is nothing to fill or tie off. It also gives the same weight every time it is reused.
Can SB-Weights be embossed with our company name?
Yes. Company branding can be embossed into the base, which helps hire fleets and contractors identify their stock across sites. Email sales@securasite.co.uk with your logo and the quantity you need, and our team will confirm minimum order quantities and lead times for branded orders.
Why buy from Securasite rather than a general supplier?
We supply trade buyers from five UK depots, and our sales team is available Monday to Friday, 8am to 5:30pm. We hold Constructionline and CHAS Elite accreditations, and white label delivery is available on request. SB-Weights can go out on the same order as your barriers and other site equipment.
