## Description

These heavy duty gas struts offer dependable lift and controlled closing for lids and hatches that weigh between 38 and 50 LB, making them a practical choice for sheds, basement doors and similar fixtures. The set is supplied as two matched struts with L mounting brackets and basic fixings, so you can restore smooth operation to a heavy lid without complex adjustments.

## Key features

Made from carbon steel with double seals, these gas shock struts aim to resist corrosion and reduce the chance of oil leakage during normal use. The 500mm length and 200N / 45LB force rating are intended for lids approximately 750 mm to 1000 mm wide, according to the manufacturer, and they come with 4 mounting brackets and 4 nuts. Note that screws are not included and you should measure the lid weight before fitting to confirm suitability.

## Specifications

- Name: Koaudb 500MM 200N/45LB Gas Struts
- Size: 500MM
- Capacity: 200N / 45LB
- Material: Carbon Steel
- Included: 2 Gas Struts, 4 Mounting Brackets, 4 Nuts

## Usage tips

If the struts feel too strong when closing, you can alter the mounting position on the lid towards the hinges to reduce closing force. Take care not to compress the struts by hand when fitting or testing, and ensure the lid weight is within the recommended range before installation. It’s a good idea to select screws appropriate to the thickness of your mounting surface, as these are not supplied.

## What’s included

The pack contains two gas shock struts, two L mounting brackets per strut and four nuts. Screws are excluded to allow for different panel thicknesses and to avoid drilling unsuitable fixings. Consider a modest limitation: these struts suit heavier lids but will not be effective for very wide or much lighter panels under 38 LB.
