A simple and practical Wichard accessory designed to support 55mm and 70mm sheave blocks on swivel bases, travellers and other compatible installations.

The Wichard #32550 Stand-Up Spring is a block accessory designed specifically for compatible blocks with 55mm and 70mm sheaves.

According to Wichard, the spring is designed to maintain the block on its base and is recommended for applications including swivel bases and travellers.

It provides elastic support underneath the block, helping maintain a more practical position while still allowing the block to move according to the direction of the line.

For 55mm & 70mm Sheave Blocks

The Wichard #32550 is specifically intended for compatible blocks with:

55mm Sheaves

70mm Sheaves

This makes it the larger alternative to the Wichard #32540 spring, which is intended for 35mm and 45mm sheave blocks.

Selecting the correct spring according to the block size is important for proper installation.

What Does the Stand-Up Spring Do?

The purpose of the #32550 is straightforward:

It Supports the Block on its Base

A block installed on a traveller, swivel base or another suitable attachment can move or fall sideways when it is not being pulled into position by the line.

The spring provides flexible support underneath the block, helping it maintain a practical position without turning the installation into a rigid connection.

Wichard specifically describes the spring as a solution for maintaining blocks on bases, travellers and similar installations.

Ideal for Swivel Bases

One of the applications specified by Wichard is:

Swivel Bases

A swivel base is designed to provide freedom of movement, so the associated block must also be able to orient itself according to the direction of the line.

The stand-up spring provides support while retaining this flexibility.

This creates a useful combination of:

Support + Freedom of Movement

Suitable for Travellers

Wichard also recommends the #32550 for:

Travellers

In these installations, the block needs to remain supported but still move and orient itself according to the operating loads and rope direction.

The spring provides a simple mechanical solution without adding an unnecessarily complex mechanism to the installation.

Keeps the Block Better Positioned

A stand-up spring can improve the practical operation of deck hardware by helping prevent the block from simply lying flat when unloaded.

This can help keep the block:

• Better positioned
• Supported at its attachment point
• Ready for the line
• Free to move when loaded
• More organized within the deck installation

The result is a cleaner and more functional block setup.

Flexible Support Without a Rigid Connection

The purpose of the spring is not to lock the block permanently in one orientation.

Instead, it provides flexible support.

When the line changes direction, the block can move accordingly. When the load is reduced, the spring continues to provide support at the base.

This is particularly useful on sailing hardware where line angles and loading directions can change during operation.

Technical Specifications

Wichard specifies the #32550 for blocks with 55mm and 70mm sheaves, with applications including swivel bases and travellers.

Choosing the Correct Wichard Stand-Up Spring

Wichard #32550

Wichard lists all three spring versions within the same block-accessory family.

A Small Upgrade for Your Block Installation

The #32550 is a simple component, but it can make a block installation more practical.

It provides support underneath the block so that the hardware maintains a more useful position while still having the freedom of movement required for the rope.

This is particularly useful in deck arrangements where the block is attached to a swivel base or traveller.
