Spacer is a metal part which is connected as a medium between the rail & the post & sharply reduces the impact momentum by absorbing much of the impact energy. This part has been first manufactured by an ITALIAN company & tested by the related authorities & now widely in use throughout Europe .

Technical specifications of the spacer
Types
Spacers are made in two types of single & double sided. The latter is used in low width refuges which also reduces the number of required posts.
Thickness of metal sheet
Thickness of the sheet used is 3mm & per location of application, it is coated by cold or hot galvanized or electrostatic paint method. The following can be regarded as the advantages of using this product:
1- It acts as a damper, thereby deceasing the impact energy.
2- Causes less damage to the post on impacts, thereby reducing maintenance costs.
3- When using double sided spacer, one post is saved per spacer.
4- Regarding the distance of the post & front surface of the rail, the post can be located on more appropriate places if necessary. In the current mounting procedure, sometimes the rails are mounted before or after the proper location due to urban limitations & this disadvantage can be avoided by using the spacer.
5- This product can be readily mounted on the existing guardrails. Accessories are provided for such installations & only required holes must be drilled on the posts.
