Radial arm drills usually have trip devices of varying varieties, not guards, unless they are really large radial arm drills in which case they usually have bespoke distance guards or similar.

Ours uses DC injection braking. Stops the drill in less than a quarter of a revolution when tripped.

The drill has trips etc fitted but there is no guarding around the drill or spindle, yes it is a large machine but proximity guards not viable.
In terms of the DC injection brake, just too hard on the motor but thanks anyway.
I need a bespoke off the shelf supplier of guards that are telescopic and protect operator from contact with drill and/or spindle. I have a few suppliers bookmarked but not quite what I'm looking for. I know you can get these type of guards just don't know where.

Turtle as a matter of interest can I ask why you think that the trips aren't effective in your case?
The whole point of trips is that the danger area isn't guarded as such but the motion of the spindle and drill would stop before serious injury occured. Though not ideal it is an accepted standard on old radials. Most companies find guarding not be practicable for the work they do.
It would be interesting to know what your problem is. Perhaps we could also suggest other solutions then?

In most cases the trip is a telescopic arm not unlike a car aerial. The trip does not stop contact with the drill and/or spindle until it is physically activated. e.g if the operator was to start drill and then say brush cutting area with hand his hand can come in contact with rotating machinery, by this point the damage is done long before he can hit the trip. The trip also doesn't stop machine instantly hence ahoskins suggestion for a dc injection brake.(good idea but not practical)
Its a simple question I am looking for a supplier of off the shelf telescopic guards for radial arm drills. I spent a lot of years on the tools and I have seen these type of guards.

Yes thank you I know what the type of telescopic trip is and how it operates (I may be female but I am experienced in such things) and as I said it is not perfect but is considered an acceptable standard on old machines, with larger machines being enclosed with interlocked guards or the use of pressure mats etc. Depends on what work is being carried out. It is also not uncommon that DC breaking is not possible on older machines.
If you want fixed guards then fine, I was just trying to find out your reasoning.
Although ahoskins also didn'lt answer your question but offered a different solution he gets "a good idea" in response whereas I get patronised with how a trip on a radial arm drill operates and brushed off.
I won't bother next time. I'll get back to polishing my nails.

HSE in the good old days had a good book on the guarding of drilling machines - have had a look but it clearly has gone out of print - seem to recall that recommended the telecopic (looks like a radio aerial) type guard. Try below supplier????? www.halcyondrives.com/attachments.do?attachment=34

It's often the case that operators will not use the telescopic "car aerial" device as intended as they say that the swarf trips the drill too frequently. It is often seen fully retracted and "out of the way".
Beware of relying on a device that won't be used as intended or expected.

That's a training and supervision issue, as exactly the same thing can be said about telescopic guards (and other types of guards)
