Specifying Beamclamp
Specifying the Correct BeamClamp® Product
It is important to select the correct Product Type, tail length, and packing shim requirement to suit your application. Unless using an adjustable tail Type BK1 the combined tail length plus the thickness of the shim(s) must be equal to the thickness of steel being clamped. The following tables are designed to assist you in selecting the appropriate combination.
The following steps will help in using these tables correctly:

Select the type of clamp you wish to use: BA, BB, BT, BW, BK1 or BY.

Select the bolt size you wish to use. The load capacity for each product is stated on the individual product pages. LNA Solutions recommends that SAE Grade 5 Bolts are used.

When connecting to wide flange beams or parallel flanges, refer to steel guides to find the flange thickness.

Using the Tables 1, 2, or 3, select the appropriate tail length and packing.
Notes:
A plus sign (+) between any of the above designations means that there is a packing required in addition to the clamp. Combinations of BH1, BF1, BG1, BF2, BG2, BH2, BF3 and BF4 packings are used.
Where ˝2 x˝ or ˝3 x˝ is indicated, use 2 or 3 as the multiplier to get the number of packings needed to suit the given flange thickness.
Key

1 = Short Tail Type BA, BB, BT, BW or BY

2 = Medium Tail BA, BB, BT, BW or BY

3 = Long Tail BA or BB

BF1 = Type BF1 packing must be used

BG1 = Type BG1 packing must be used

BH1 = Type BH1 packing must be used

BF2 = Type BF2 packing must be used

BG2 = Type BG2 packing must be used

BH2 = Type BH2 packing must be used

BF3 = Type BF3 packing must be used

BF4 = Type BF4 packing must be used

OK = Product is suitable without any additional packings

X = Not recommended
