Product description
B2 Priority Sign – Stop, 100 cm, Class II
A 100 cm STOP sign with class II prismatic sheeting: the large format in SR 1848-2, for junctions on national roads and for level crossings without barriers, where the stop has to be seen from a distance.
Why class II
Class II (RA2) prismatic sheeting returns roughly three to four times more headlight to the driver than class I sheeting, so the sign can be seen from further away at night and stays legible when viewed at an angle. SR 1848-2 requires prismatic class 2 or 3 sheeting in areas with many light sources, such as streets with public lighting, shop windows and advertising, where a class I sign gets lost in the background. Class II sheeting has a guaranteed 10-year service life, against 7 years for class I.
Where it goes, under SR 1848-1:2024
It goes on the minor public road or cycle track, at junctions without good visibility, or where a cycle track or cycle road meets the carriageway, as close as possible to the edge of the priority road, but so that stopped vehicles do not block pedestrians crossing. It is also used at crossings with a railway without barriers, other than an industrial line, where it goes with the A47 or A48 cross.
At junctions, signs on the minor roads are placed so that their face cannot be seen from the priority road. At acute-angle junctions the sign is set back from the edge of the priority road; if it stands more than 10 m back, the P4 additional panel with the distance goes under it.

Mounting and size
Fixings for the post are included: 2 clamps for Ø48 mm posts and 4 bolts with nuts; clamps for Ø60 mm posts are available on request. The bottom edge of the sign goes 1.50–2.50 m above the road or kerb, and the edge nearest the road 0.50–2.0 m from the road platform.
The post is ordered separately. For a fixed installation in a concrete foundation: the galvanised Ø48 mm post, 300 cm. For temporary use, with no foundation: the Ø48 mm tripod post, 120 cm. On concrete or paving, where you cannot dig: the Ø60 mm flange post, 300 cm, bolted down; for it, ask for the Ø60 mm clamps when you order.
100 cm is the large format in SR 1848-2, for national roads; motorways call for 120 cm. County roads and streets only need the normal 80 cm format: the B2_80_II or, with class I sheeting, the B2_80_I.
? Frequently asked questions
Where does it go?
It goes on the minor public road or cycle track, at junctions without good visibility, or where a cycle track or cycle road meets the carriageway, as close as possible to the edge of the priority road, but so that stopped vehicles do not block pedestrians crossing. It is also used at crossings with a railway without barriers, other than an industrial line, where it goes with the A47 or A48 cross.
How does it differ from the class I sheeting version?
It is larger than the B2_80_I: 100 cm instead of the normal format, and the class II (RA2) prismatic sheeting returns three to four times more light, with a guaranteed 10-year service life instead of 7.
When is class II sheeting mandatory?
SR 1848-2 requires prismatic class 2 or 3 sheeting in areas with many light sources: street lighting, shop windows, advertising, dense urban areas. Elsewhere, class II is chosen for better visibility on fast roads and where the sign is seen at an angle.
Which fixings come with it?
The pack holds 2 clamps for Ø48 mm posts and 4 bolts with nuts. Clamps for Ø60 mm posts are available on request, a better fit for large signs or windy locations.
When do I use the B1 and when the B2?
Which post should I order?
The post is ordered separately. For a fixed installation in a concrete foundation: the galvanised Ø48 mm post, 300 cm. For temporary use, with no foundation: the Ø48 mm tripod post, 120 cm. On concrete or paving, where you cannot dig: the Ø60 mm flange post, 300 cm, bolted down, for which you ask for the Ø60 mm clamps when you order.
How high is it mounted?
The bottom edge of the sign goes 1.50–2.50 m above the road or kerb, and the edge nearest the road 0.50–2.0 m from the road platform. The sign must be visible from at least 50 m in built-up areas and 100 m outside them.
Is the sign CE marked?
Yes. It is CE marked and complies with SR EN 12899-1:2007, the European standard for vertical road signs, and with SR 1848-1:2024, SR 1848-2:2011 and SR 1848-3:2011. The sheeting and the paint resist UV and weathering.
