The Checklock SQ® is manufactured in the UK with premium stainless steel and distributed globally. Simple yet so innovative, the way in which the Checklock SQ® works, is by simply squeezing the two handles together with the forefinger and thumb to loosen the two coils enough for two adjacent nuts to pass through. When you release the two handles, the Checklock SQ® will create tension, the coils will tighten, grip and retain the wheel nuts to reduce the likelihood of wheel nuts loosening or even backing up from the wheel hub completely. Absolute minimal maintenance time and costs, this product requires no fitting tool and is durable and reusable.
The Checklock SQ® is a newer, better developed wheel nut retainer that supersedes the Checklock®. The Checklock SQ® is experiencing high levels of growth and has developed to become one of the core products at Checkpoint Safety with global demand increasing weekly. Available in a wide range of sizes, the Checklock SQ® aims to cover a broad scope of applications throughout the commercial vehicle sector.
The primary functions of Checklock SQ® are to:
Retain wheel nuts to lower the likelihood of them loosening
Greatly reduce the likelihood of wheel nuts backing away completely from the wheel hub
Provide a clear commitment to roadworthiness and professionalism to other road users, customers, health and safety, road and transportation associations such as DfT, HMRC Customs and Excise, VOSA, HSE, FTA and RHA
Can comfortably incorporate a wheel overheating indicator function
The primary benefits of fitting Checklock SQ® are:
✓ Improved safety of fittings where nuts are a critical structural component, such as on vehicle wheels and industrial/commercial structures
✓ Much improved vehicle safety through avoiding potentially severe road accidents resulting from loose wheel nuts or wheel detachment
✓ Simple to fit, with no additional tools required, to help the reduction in maintenance time and costs
✓ Reduction in vehicle downtime
✓ Improved professionalism, roadworthiness and safety related company image or reputation
✓ Cost effective solution to implement
✓ High quality premium stainless steel reuseable product
The Checklock SQ® design is intended for vehicles with wheels that don’t have trims/step rings. The Dustite LR® wheel nut indicator, however, can be used in circumstances where step rings/trims are fitted on the wheels of the vehicle. Once the wheel nuts on the vehicles’ wheels have been tightened to the manufacturers recommendations, the Checklock SQ® can be fitted. It is NOT recommended that the Checklock SQ® is used as a direct replacement for a safe, sound vehicle wheel maintenance schedule. These should be fitted in accordance with the product guidelines and used in combination with a robust system of wheel checks.
