For scaffolding formwork temporary works, the hardware that locks forms together has to hold when the concrete pushes against the wall. Two Sandbaggy pieces solve that in different ways: a cast-iron pencil rod clamp that grips smooth or deformed rods, and a galvanized steel snap tie wedge that locks ties tight on stick-built forms. They are not interchangeable, so the right pick depends on how your form is built and how many pieces you need.
Quick verdict
Pick the Sandbaggy Heavy Duty Pencil Rod Clamp (w/ Bolt) if your form uses pencil rods, especially for curved or battered walls, and you want a reusable single clamp. Pick the Sandbaggy Galvanized Steel Snap Tie Wedges (2 ⅜" x 6 ⅛") if you are setting standard or heavy-duty snap ties on double 2x4 walers and want a 10-pack with a galvanized coating.

Where each product wins
The rod clamp wins when your form is rod-based. It is cast malleable iron, has three 3/16-inch nail holes for fastening, and is reusable. The listing shows safe working loads of 1,125 lb for 1/4-inch rods and 2,250 lb for 3/8-inch rods, and it accepts smooth or deformed rods, which is useful for battered or curved wall layouts.
The snap tie wedge wins when you are locking ties across a panel. Each wedge is 11-gauge hot-dip galvanized steel, weighs 0.45 lb, and is rated up to 3,250 lb. It works with standard and heavy-duty snap ties, and a 10-piece pack means you can cover a full form without ordering individual pieces.
Product notes
Sandbaggy Heavy Duty Pencil Rod Clamp (w/ Bolt) - Concrete Formwork Clamps
Start here if your formwork relies on pencil rods. The cast malleable iron body is construction grade, the bolt lets you set the grip, and the three nail holes give you fastening points for securing the clamp to your form. It is reusable, and the safe working load ranges from 1,125 lb with 1/4-inch rods to 2,250 lb with 3/8-inch rods. The limitation is that the listing is for one clamp, so a wall with many rod connections means you will need several. It also works with smooth or deformed pencil rods, not as a universal tie wedge.
Sandbaggy Galvanized Steel Snap Tie Wedges (2 ⅜" x 6 ⅛") for Concrete Formwork
Choose this pack when your forms are tied together with snap ties and walers. Each wedge is 11-gauge hot-dip galvanized steel and weighs 0.45 lb, with a 6.125-inch length that gives you a good purchase when driving the wedge. The galvanized coating helps with jobsite corrosion resistance, and the listing rates the wedges up to 3,250 lb. The limitation is the pack size: you get 10 wedges in one listing, and these are built for snap tie systems rather than pencil rod clamping, so they are not a substitute for the rod clamp in a rod-based form.
Final choice by use case
Use the Sandbaggy Galvanized Steel Snap Tie Wedges when you are building stick forms with double 2x4 walers and need a 10-pack for a whole panel. Use the Sandbaggy Heavy Duty Pencil Rod Clamp when your pour uses smooth or deformed pencil rods and you want a reusable clamp with a USD 6.00 listed price.
