About the product
A ciroz tensioner is a lever hand tool designed to tighten spring formwork locks used on reinforced-concrete wall, column and beam forms. In ribbed-tie and spring-clamp (ciroz) systems it helps tension the bar and press form panels toward each other, supporting a controlled form gap and more controlled tightening of connections.
Espada İskele’s lever ciroz tensioner is a site hand tool for practical tightening of formwork locks. Also searched as a ciroz wrench or lever formwork-lock tightener, it helps reduce install labour time and supports more controlled clamping.
The lever creates force that helps tighten the tie and spring lock. Place the clamp on the ribbed bar as required. Align the tool jaws with the bar and lock mechanism. Move the lever to tension the connection under control. Check that the lock is seated securely, then remove the tool.
Follow the grip point and manufacturer instructions. An unsuitable bar diameter or lock type can reduce grip and tightening performance.
Tensioners differ by force path. A lever model builds force with arm motion and suits repeated formwork connections. A jack / broken-handle model transfers force through a jack mechanism and may allow stepwise pull depending on design. Choose by clamp type, workspace and required force. This page offers the lever model; jack stock and supply are assessed separately.

What Is a Ciroz Tensioner For?
A ciroz tensioner helps tighten formwork connections before the pour. It is often preferred on wall and column forms that use a ribbed tie and spring lock. Connection hardware, the formwork system and the tightening method must suit site conditions—the tool alone does not guarantee resistance to concrete pressure.
Lock tightening
Help tighten the formwork lock on the ciroz / ribbed tie.
Panel press
Help press form panels toward each other.
Form gap
Support keeping the form spacing under control.
Repeat cycles
Make repeated tightening cycles more practical.
Labour time
Help reduce labour time during formwork install.

Frequently Asked Questions
What is a ciroz tensioner?
A hand tool that helps tighten ribbed-tie and spring formwork-lock connections on concrete forms. The lever mechanism supports controlled tensioning of the connection.
Is a ciroz wrench the same as a ciroz tensioner?
In the trade, “ciroz wrench” and “ciroz tensioner” may both describe tools used to tighten a ciroz or formwork-lock connection. Mechanism and compatibility still need checking by model.
Which forms is the lever model used on?
With a suitable connection system it can be used on wall, column and beam forms. Suitability depends on the lock and ribbed-tie characteristics.
Which bar diameters is it compatible with?
Compatibility depends on jaw geometry and the lock–bar combination. Exact diameter range should follow manufacturer data and pre-order confirmation. A typical market band is ~6–10 mm ribbed bar—confirm with Espada İskele in the quote.
Can the tensioner and formwork lock be bought together?
Combined supply depends on stock and availability. State bar diameter and lock type so compatible items can be quoted together.
How do I learn the ciroz tensioner price?
Current price is learned by requesting a quote from Espada İskele with quantity and delivery details. Use Get a quote on this page—there is no fixed list price.
