From The Anvil Narrow Spring Unit Cassette

The From The Anvil Narrow Spring Unit Cassette is a door-handle accessory designed to increase spring tension and improve the feel and operation of older or weaker locks and latches. It is used behind the door handle, helping support the handle action where existing tension has become worn over time.

The cassette is intended to be cut into the face of the door so it can sit flush behind the handle, keeping the fitting discreet once installed. For best results, the guidance for this product is to fit one cassette on each side of the door (depending on your door and handle setup).

What to expect

• Purpose: improves tension and functionality for old or weak locks and latches
• Position: fits flush behind the door handle when recessed into the door face
• Quantity: sold individually, allowing you to buy one or two as required
